Energy is everywhere and also comes in many forms, v the 2 most common forms well-known as potential energy and also kinetic energy.

You are watching: Which of the following is not an example of potential energy?

despite they’re very different in terms of just how they communicate with the physics world, castle have details aspects that make them complementary to one another. However to understand just how they work, you very first need to understand what they room — and the meaning of power itself.  

What Is Potential and also Kinetic Energy?

Before understanding either form of energy, it’s crucial to recognize what energy really is. In the easiest terms, power is the capability to perform work, i m sorry is as soon as a pressure is used to things and that moves<1>. 

Potential energy is among the 2 main species of power in the universe. It’s fairly straightforward, return slightly challenging to grasp intuitively: the is a type of power that has actually the potential to do work yet is not proactively doing work or applying any force on any other objects. Potential energy of things is discovered in its position, no its motion. That is the energy of position.  

When objects space displaced from positions of equilibrium, lock gain energy that was stored in the objects prior to being knocked the end of equilibrium through elastic rebound, gravity, or chemistry reactions. This is best demonstrated in things like an archer’s bow, which shop the energy that is developed from pulling earlier the bowstring. The potential energy stored in the pullback is responsible for the power that wake up upon release, i m sorry is recognized as kinetic energy.  

Understanding kinetic power is intuitively easier since it’s more obvious that relocating things have actually energy.  

Kinetic energy is produced when potential energy is released, spurred right into motion by heaviness or elastic forces, amongst other catalysts. 

Kinetic power is the energy of motion. When occupational is done on things and that accelerates, it increases the kinetic energy of one object. The most important factors that identify kinetic power is the movement (measured together velocity) and the fixed of the object in question.  

While mass is a global measurement, the activity of things can occur in many different ways, consisting of rotation about an axis, vibration, translation, or any combination of these and also other motions<2>. 

There space three subcategories that kinetic energy: vibrational, rotational, and also translational.  

Vibrational kinetic power is, unsurprisingly, brought about by objects vibrating. Rotational kinetic energy is created by moving objects, while translational kinetic power is led to by objects colliding v one another.  

These three subcategories the kinetic energy comprise nearly every one of the power in motion throughout the known universe. 

What are the Differences between Potential and also Kinetic Energy? 

The main difference between potential and also kinetic power is the one is the energy of what deserve to be and one is the energy of what is. In various other words, potential power is stationary, v stored power to it is in released; kinetic energy is power in motion, proactively using power for movement.  

Another important distinction is velocity. This measure is the communication of kinetic energy, yet has actually nothing to do with potential energy. In fact, velocity is the many important part of the equation when determining the amount of kinetic power for any given object, and it is missing in the potential power equation<3>.  


What Is the Relationship between Potential and also Kinetic Energy? 

Although this primary forms of power are really different, they are complementary to one another.  

Potential energy constantly leads come kinetic energy when the is released<4>, and kinetic power is required to permit an object to store energy as potential, in one means or another. Because that example, a rock on the edge of a cliff does not directly need kinetic power to store the potential power that will send it under the eroding cliff face. However the act of erosion to acquire the absent to the edge calls for kinetic energy. Therefore, the rock needs it because that its potential energy. 

Given that these are the two main forms of energy in the world, specifically on the person scale, yes sir a continuous push and also pull in between potential energy and kinetic power in day-to-day life. 

What Are examples of Potential and Kinetic Energy? 


Although the an interpretation of both potential and kinetic energy may seem pretty straightforward and also simple, it’s tho not constantly easy come tell which form of energy is current for specific objects or processes.  

1) Planets 

The activity of planets approximately the sun and also other stars in the galaxy is kinetic power at work. As they are attracted towards the large objects at the facility of their respective orbits, because of the strong gravitational pull, they loss towards the facility of the mass. This outcomes in one orbiting activity — and also all activity is a type of kinetic energy. <5> 

2) Rubber Bands 

Rubber bands deserve to be classified together both potential and kinetic energy, depending upon the state the the band. When an elastic is stretched, that loaded v potential energy; when released over there is a change to kinetic energy. This is especially true if the elastic is transporting another object, such similar to a absent being flung from a slingshot. <6> 

3) Rivers 

Rivers room strictly kinetic power at work. The water is continually moving, and also all that motion is constantly developing kinetic energy. The only time a river might have potential energy is if it is dammed, through the artificial reservoir storing power to be provided when necessary along a hydroelectric dam. <7> 

4) certain Variations 

There are details variations of power within both kinetic and also potential energy classifications. While part variations, such together the potential power stored in batteries, are easily apparent, others room not as easy to identify.  

What Is the Potential energy of one Electron? 

Electrons room in motion, for this reason they save kinetic energy. This is just one of the ideal examples the a nonphysical object transferring kinetic energy.  

However, the still feasible to discern the potential energy that an electron has stored. To uncover this potential energy, it requires a complicated formula<8>: 

U(r) = -qeV(r) = -keqe2/r 

The total energy is the amount of the electron’s kinetic energy and its potential energy, i beg your pardon is represented by an even more facility formula<8>: 

KE(r)+PE(r)=-½keqe2/r=(-½)(9*109)(1.60*10-19)/(5.29*10-11) J = -2.18*10-18 J 

Is a Battery Kinetic or Potential Energy? 

Batteries room a kind of chemical energy, with power stored in the bonds of molecules consisted of within the battery acid at their core. The an essential word right here is “stored” — an interpretation batteries space a form of potential energy, i m sorry is just how all chemical energy is share <9>. Biofuels and fossil fuels are other instances of stored chemistry energy. 

Is electric Energy Potential or Kinetic? 

Electrical power is classified as potential energy before it’s released and used in the form of power, which is most frequently harnessed and also used as electricity<10>. However, once it is convert from that is potential state, electric energy can become one the the subtypes that kinetic energy, consisting of motion or sound, amongst others. 

Is Sound energy Potential or Kinetic? 

Sound can be thought about both forms of power at the exact same time, despite the primary way we endure it is in kinetic form. Sound energy in air, i beg your pardon is created from longitudinal tide that develop motion in gas molecules, is kinetic. In solids and liquids, which carry sound lot farther than through air, this is both kinetic and potential power at work.<11>  


Potential power can be damaged down right into two subforms the energy. Every of this subforms are types of save on computer potential energy. However the method in i m sorry they are stored — and also released — are vastly different. 

What Is chemistry Potential Energy? 

Chemical potential power is save on computer in molecule bonds, i beg your pardon are likewise known together chemical bonds. When these bonds space broken, the save potential energy is released and gives turn off varying degrees of kinetic energy, depending upon the strength of the bonds.<14> 

What Is Gravitational Potential Energy? 

Gravitational potential power is stored in the object due to the potential because that the force of heaviness to relocate it and also pull it in the direction of the Earth. The amount of save on computer potential gravitational power depends directly on the mass of the thing and, much more importantly, its height over the ground.<15> 

The Science 

The 2 subforms of potential energy covered above duty primarily v the 2 most simple fields the science. However, the system that governs potential energy in the realm of physics is much various than the device that governs in the kingdom of chemistry. 

What Is Potential energy in Physics? 

Potential energy in the realm of physics is in the form of gravitational potential energy. Gravity is possibly the many important aspect of physics, as it is the basis of basic relativity, i beg your pardon the entire contemporary world is based upon. That is this force that developed potential energy in physics terms.<16> 

What Is Potential power in Chemistry? 

Potential power in the realm of chemistry is in the kind of chemical potential energy. This is power stored in molecular bonds, i beg your pardon is the communication of chemistry and chemical reactions. Save on computer potential power is released v these chemistry reactions.

What are the Formulas for Kinetic Energy and also Potential Energy?

The formulas for potential and kinetic energy are reasonably straightforward, but they room by no way simple.  

Kinetic energy can be found using the formula: KE=12mv2 

m = massive (kg) v = velocity (m/s) 

Gravitational potential energy can be found using the formula: W = m×g×h = mgh 

m = massive (kg) g = acceleration as result of gravitational ar (9.8 m/s2) h = height (m) 

Elastic potential energy can be discovered using the formula: U=12kx2 

k = spring pressure constant x = stretch size (m) 

The units used to measure each of these forms of energy is the exact same as every the other develops of energy: the Joule (J), i m sorry is same to 1 kg.m2.s-2.<17> 

Energy Everywhere 

You have actually learned about several develops of energy — in addition to some pertinent instances — yet there is much an ext that needs to be covered to fully understand the principle of energy.  

However, understanding the two main creates of energy that permeate not only everyday life, but additionally the core of physics throughout the universe, is a great starting point and sets the foundation for any kind of deeper dives right into the nature of power itself.  

There are just two things that absolutely need to be remembered: stationary objects with stored energy have potential and moving objects are kinetic.
