The communication and an interpretation of these two energies are critical to our understanding of the world about us. Let’s take it a look at what potential and kinetic energy mean, the relationship in between them, and some instances of each. 

What Is Potential and Kinetic Energy, and also What are Their Differences? 

Potential energy is stored energy. An item has a measurable quantity of potential energy depending on where the located and how the relates to various other objects roughly it — the energy of position.

You are watching: Why do the particles of objects have both kinetic and potential energy?


An apple on the floor has very small potential energy. Background it to the top of a skyscraper, and suddenly it has actually a lot of potential energy. That can loss to the soil under the pressure of gravity. The can also interact with other objects top top its descent, such together striking a paris bird or landing top top a automobile roof and also damaging it. 

When the apologize is descending, the potential energy has become kinetic energy, i m sorry is the power of motion. Kinetic energy is the energy a human being or an object has as result of its motion — in this example, the fallout’s apple. A parked bicycle on height of a hill has actually potential energy, which becomes kinetic power once you start riding that downhill. 

Both of these energies are measured in joules. Power is never ruined or shed when transforming from potential energy to kinetic power — it is just transformed native one energy form to another. This is known as the law of conservation of energy.<2> 

The potential energy of an object cannot be transferred to an additional entity – you can not suck the potential power out the the to apologize atop a skyscraper. Kinetic power is transferable, as witnessed v the falling apple’s kinetic energy damaging a vehicle or hitting a bird.  

What Is the Relationship in between Potential and Kinetic Energy? 


The relationship in between potential energy and also kinetic power is that potential energy can transform right into kinetic energy. 

Potential energy is place relative. In various other words, it changes depending on an object’s height or distance and also the mass of the object. Kinetic energy alters depending on one object’s speed and also its mass. 

If we think around a waterfall, some still water in ~ the peak of the waterfall has potential energy. That isn’t moving and also hasn’t gone over the edge. The water flowing from the waterfall has actually kinetic energy as that flows.<3> 

A pendulum is terrific example of this relationship. As the pendulum ferris wheel ever greater upwards, that is potential energy increases till it reaches its optimum in ~ the highest suggest of the swing. In ~ the optimal of the arc, the potential energy turns into kinetic power as the swings ago down.<4> 

What Are examples of Potential Energy? 

There are 2 primary species of potential energy: gravitational potential energy and elastic potential energy. 

The gravitational pressure of the Earth reasons gravitational potential energy. When a human jumps from a high dive board, they land with much pressure (and a splash) into the swimming swimming pool below.  

The Earth’s gravity offers the diver’s gravitational pressure (their weight) to create the kinetic energy (movement) that brings the diver into the pool. At the height of the diving board, we have the right to talk around the diver’s gravitational potential energy. 


Having identified the main species of energy, we have the right to look at more specific examples and also deduce if they have actually kinetic or potential energy.  

What Is the Potential power of one Electron? 

Atoms are consisted of of protons, neutrons, and electrons. Atoms have the right to transfer potential and kinetic energy.  

An atom has actually a nucleus, and also electrons orbit the nucleus, i m sorry is kinetic energy. Intend we apply energy or pressure to the atom. In the case, it increases the electrons’ kinetic energy and they begin to move much more quickly. Eventually, the electrons jump out into a wider orbit the the nucleus. This electron has now stored this energy, this potential energy.<7> 

At part point, the electron will certainly release this potential energy, converting right into kinetic energy as it return to its previous, smaller sized orbit. The potential energy is released together visible irradiate or heat, both varieties of kinetic energy.<7>  

An electron’s complete energy is the sum of the kinetic and potential energy.<8> 

For an ext details, think about this formula<9> because that calculating the potential power of one electron.  

Is a Battery Kinetic or Potential Energy? 

Batteries space a type of electric potential energy. They create electrical power via a chemistry reaction the occurs as soon as positive and negative charges room separated.<10> 

When you revolve on a battery-operated device, its potential power stores the chemical and electrical energy are released and become other kinetic power forms. Once turned on, a handheld torch releases light energy and also thermal energy, a kind of kinetic energy. A battery-powered singing and also cycling toy monkey atop a cycle will develop mechanical energy as that cycles around, and also sound power while to sing its song.<11> 

A battery shop potential energy that transforms right into kinetic energy. The mobile call battery you might be reading this on shop potential energy and also converts it come kinetic power (light, thermal), allowing your phone to function. 

Is electrical Energy Potential or Kinetic? 

Electrical power can it is in potential or kinetic energy. It results from the flow of an electrical charge. Together discussed, power can be viewed as the work required to move an item or subject it come force. For electrical energy, this force, energy, or “work” is the electrical attraction or repulsion in between charged particles.  

The existing of power most typically talked about occurs once these fee particles travel v a wire.  

Like a battery, electric energy is frequently potential energy until some force or is applied to do the fee particles carry out some work and also become kinetic energy. As soon as you move on your light in ~ home, the potential energy travels under the wire and is converted into light and also thermal energy.<12> 

It’s enjoyable to think about the conservation of energy and how, because that example, renewable energy like wind power takes energy from wind and converts it into usable electric energy because that our homes.  

Is Sound power Potential or Kinetic? 

Sound power comes in both potential and also kinetic power forms. Sound energy is exit by vibrating objects in the form of a wave.<13> 

An excellent example of sound power is a tuning fork. When it lies ~ above the table, it has actually the potential to develop sound energy, which is potential energy. As soon as you to win it, the vibrates and also emits sound waves. This waves oscillate and travel, i m sorry is kinetic energy.  

Sound travels about four times much faster in water 보다 in air. In ~ sea level, the speed of sound is approximately 767 miles per hour (1,230 kilometers per hour).<14> 

Is Thermal power Potential or Kinetic? 


Thermal power is likewise called heat energy. Psychic the excitable electrons and atoms from earlier? Thermal energy is developed when these atoms and molecules are relocating faster. They room moving much more quickly because of the rise in temperature.<15>  

We should stay in ~ a molecule level to recognize that thermal energy is likewise potential and kinetic energy. Every matter, comprised of atoms and molecules, is constantly moving. They have actually potential energy. Anytime a problem heats up, the molecules and atoms in ~ move more quickly, banging into each other and also releasing thermal energy as heat.<15> 

Think about a kettle boiling. The water molecules move much faster as the water heats, and this activity is kinetic energy. Once the water boils, its vapor moves. The thermal power released indigenous the atoms and molecules has created kinetic energy. 

More examples encompass the heat from an electric heater or as soon as you put food in the oven to bake; when you placed cold milk in a hot drink choose tea, some of the tea’s thermal heat is passed to the milk.<16> 

Is Radiant power Potential or Kinetic? 

Radiant energy is a type of kinetic energy. That is the energy of electromagnetic waves that deserve to travel with space.  

The sunlight is a vast resource of radiant energy on Earth. For example, tree absorb electromagnetic waves and, via photosynthesis, produce their food. Once the sun’s radiant energy touches our skin, the waves make our skin’s molecules move faster, and also we feeling warmer.<17> 

We have the right to see radiant energy waves together light energy — the only form of energy the human eye can see. Radiant energy’s magnetic tide can likewise be invisible, such as X-rays and also radio waves.<18> 


The principles of energy, based upon Newton’s Laws, have helped us recognize the world around us and also the universe.  

What Is Potential energy in Physics? 

Potential energy is the save on computer or latent power in an item at rest. It’s fundamental to countless physics-related concepts because its laws organize true on any level, native the planetary come the atomic level. 

The potential power of an object is measurable. The quantity it has depends on wherein the thing is located — its energy of position — and also the fixed of the object. 

Many objects transform your potential power into kinetic energy.  

What Is Potential energy in Chemistry? 

Chemical potential power is released when atomic binding stored in compounds and elements are broken via chemical processes. This chemical energy is then provided in other ways, in what is referred to as work. Energy and work are essentially the exact same things — occupational is energy in motion. 

 What Is Kinetic Energy and also Potential power Formula? 

Potential energy, or work, is measure up in joules, named after James Prescott Joule, an English mathematician whose work developed the formula around energy and also its transference.<25>  

Joule is written through the prize J in the international System of systems (SI), and the formula is composed thus:<25> 

m is the massive of our object<26> h is the elevation of ours object<26> g is the acceleration because of gravity, a consistent all end the Earth<26> 

If us lift our object from the floor to give it potential energy, the pressure that would certainly make it accelerate in the direction of the ground is referred to as the magnitude of force (F). Newton’s second law is F = mg.

Which gives: Gravitational Potential power = mgh<26> 

If we lift a 200 pounds human 100 feet in the air, their potential energy is 27,116.36 joules. Try this handy calculator to calculation potential energy. 

The kinetic power of an object is likewise measured in joules. Anything the is moving has kinetic energy, however various factors affect how much kinetic energy an item has. 

The very first factor is speed. If two identical objects are relocating at various speeds, the quicker object has an ext kinetic energy. A moving automobile traveling in ~ 2 miles every hour has actually a lot less kinetic energy — the energy of movement — than the same automobile traveling 100 miles per hour. 

The second factor is mass. If 2 objects are relocating at the same speed, however one that the objects has more mass, the more heavier object has an ext kinetic energy. Utilizing the vehicle analogy again, a bike going at 20 miles per hour has less kinetic energy than a dumpster going at the very same speed. 

Kinetic power is noted as E, Ek, or KE. That is half the massive of an item multiplied by its velocity squared. So the is proportional to mass (m) and proportional to the square the its velocity. The formula is written:<27> 

Kinetic energy: KE = ½ mv2 

If our 200-pound human is running at 8 miles per hour, your kinetic power is J 580.15 joules.  

For more details, you deserve to read an ext about power formulas.<28> 

It’s all Energy, Potentially 

Potential and also kinetic energy are part of the enormous power of our universe. They’re different forms that energy, but they are very closely linked and also are measured making use of the exact same units (joules). 

Energy is never lost; it simply transforms right into other develops of energy. It’s beneficial to know where power comes from and also how it effects your day-to-day life when selecting an power supplier. Ultimately, it helps us comprehend the environment and also our place in the universe.
