Energy is everywhere and also comes in many forms, through the two most usual forms recognized as potential energy and kinetic energy.

You are watching: Which has the greatest potential energy

despite they’re very different in terms of just how they connect with the physics world, they have particular aspects that make castle complementary to one another. However to understand exactly how they work, you an initial need to understand what they room — and the meaning of energy itself.  

What Is Potential and also Kinetic Energy?

Before knowledge either type of energy, it’s vital to know what energy really is. In the simplest terms, energy is the capability to execute work, which is when a pressure is applied to an object and the moves<1>. 

Potential power is one of the two main species of power in the universe. It’s fairly straightforward, return slightly daunting to understand intuitively: the is a type of power that has actually the potential to perform work yet is not proactively doing work-related or applying any type of force on any other objects. Potential energy of an object is found in its position, not its motion. The is the energy of position.  

When objects are displaced from location of equilibrium, they gain power that to be stored in the objects prior to being knocked out of equilibrium by elastic rebound, gravity, or chemistry reactions. This is ideal demonstrated in things like one archer’s bow, which shop the energy that is developed from pulling ago the bowstring. The potential power stored in the pullback is responsible for the energy that wake up upon release, i beg your pardon is recognized as kinetic energy.  

Understanding kinetic power is intuitively easier because it’s much more obvious that moving things have actually energy.  

Kinetic power is developed 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 excellent on an item and it accelerates, it increases the kinetic power of an object. The many important factors that recognize kinetic power is the movement (measured as velocity) and the mass of the object in question.  

While mass is a universal measurement, the activity of things can take place in plenty of different ways, consisting of rotation around an axis, vibration, translation, or any mix of these and other motions<2>. 

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

Vibrational kinetic energy is, unsurprisingly, resulted in by objects vibrating. Rotational kinetic power is produced by relocating objects, while translational kinetic power is resulted in by objects colliding with one another.  

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

What are the Differences in between Potential and also Kinetic Energy? 

The key difference between potential and kinetic power is the one is the energy of what have the right to be and one is the energy of what is. In various other words, potential energy is stationary, v stored power to be released; kinetic power is power in motion, actively using energy for movement.  

Another important difference is velocity. This measure is the basis of kinetic energy, yet has actually nothing to execute with potential energy. In fact, velocity is the many important part of the equation as soon as determining the amount of kinetic energy for any given object, and also it is nonexistent in the potential energy equation<3>.

What Is the Relationship in between Potential and also Kinetic Energy? 

Although these primary forms of energy are really different, they are complementary to one another.  

Potential energy always leads to kinetic energy when that is released<4>, and kinetic power is required to permit an object to store power as potential, in one method or another. For example, a rock on the sheet of a cliff go not straight need kinetic power to store the potential power that will certainly send it under the eroding cliff face. Yet the act of erosion to obtain the absent to the edge needs kinetic energy. Therefore, the rock needs it because that its potential energy. 

Given the these are the 2 main forms of power in the world, particularly on the human being scale, yes sir a continuous push and also pull in between potential energy and kinetic energy in everyday life. 

What Are examples of Potential and Kinetic Energy?

Although the an interpretation of both potential and kinetic power may seem pretty straightforward and simple, it’s still not always easy to tell which form of power is current for specific objects or processes.  

1) Planets 

The movement of planets about the sun and other stars in the galaxy is kinetic power at work. As they are drawn towards the huge objects at the facility of their corresponding orbits, due to the strong gravitational pull, they loss towards the center of the mass. This outcomes in an orbiting movement — and all motion is a kind of kinetic energy. <5> 

2) Rubber Bands 

Rubber bands deserve to be classified together both potential and also kinetic energy, relying on the state the the band. When an elastic is stretched, that loaded with potential energy; once released there is a change to kinetic energy. This is especially true if the elastic is transporting an additional object, such just like a rock being flung indigenous a slingshot. <6> 

3) Rivers 

Rivers room strictly kinetic power at work. The water is continuous moving, and also all that activity is constantly creating kinetic energy. The just time a river could have potential power is if that is dammed, with the man-made reservoir storing power to be provided when necessary along a hydroelectric dam. <7> 

4) details Variations 

There are particular variations of power within both kinetic and potential power classifications. While some variations, such as the potential power stored in batteries, are conveniently apparent, others are not as straightforward to identify.  

What Is the Potential energy of one Electron? 

Electrons space in motion, for this reason they save kinetic energy. This is just one of the best examples of a nonphysical object delivering kinetic energy.  

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

U(r) = -qeV(r) = -keqe2/r 

The full energy is the amount of the electron’s kinetic energy and its potential energy, which is stood for by an also 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 space a type of chemical energy, with energy stored in the bond of molecules contained within the battery acid at their core. The crucial word below is “stored” — meaning batteries space a type of potential energy, i beg your pardon is how all chemical power is divide <9>. Biofuels and fossil fuels space other examples of stored chemical energy. 

Is electric Energy Potential or Kinetic? 

Electrical energy is classified together potential energy before it’s released and also used in the form of power, i beg your pardon is most frequently harnessed and also used together electricity<10>. However, when it is converted from the potential state, electric energy can become one the the subtypes the kinetic energy, including motion or sound, among others. 

Is Sound power Potential or Kinetic? 

Sound have the right to be taken into consideration both forms of power at the same time, despite the primary means we experience it is in kinetic form. Sound power in air, i m sorry is developed from longitudinal waves that develop motion in gas molecules, is kinetic. In solids and also liquids, which lug sound much farther than with air, this is both kinetic and also potential energy at work.<11>

Potential energy can be damaged down right into two subforms that energy. Each of this subforms are species of save potential energy. However the an approach in i beg your pardon they are stored — and also released — are vastly different. 

What Is chemistry Potential Energy? 

Chemical potential energy is stored in molecule bonds, which are likewise known together chemical bonds. As soon as these bonds space broken, the save on computer potential power is released and gives off varying levels of kinetic energy, depending upon the strength of the bonds.<14> 

What Is Gravitational Potential Energy? 

Gravitational potential energy is stored in the object as result of the potential because that the pressure of heaviness to move it and pull it in the direction of the Earth. The lot of save on computer potential gravitational power depends directly on the mass of the object and, an ext importantly, its height over the ground.<15> 

The Science 

The 2 subforms that potential energy covered above function primarily with the 2 most basic fields the science. However, the system that governs potential power in the kingdom of physics is much different than the system that governs in the realm of chemistry. 

What Is Potential energy in Physics? 

Potential energy in the realm of physics is in the type of gravitational potential energy. Heaviness is probably the most important facet of physics, as it is the communication of general relativity, i beg your pardon the entire contemporary world is based upon. The is this force that produced potential energy in physics terms.<16> 

What Is Potential power in Chemistry? 

Potential power in the realm of chemistry is in the form of chemical potential energy. This is energy stored in molecule bonds, i m sorry is the basis of chemistry and also chemical reactions. Stored potential energy is released v these chemical reactions.

What room the Formulas because that Kinetic Energy and also Potential Energy?

The formulas because that potential and also kinetic power are reasonably straightforward, but they space by no method simple.  

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

m = massive (kg) v = velocity (m/s) 

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

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

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

k = spring force constant x = stretch length (m) 

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

Energy Everywhere 

You have learned around several creates of power — together with some pertinent examples — but there is much more that requirements to be spanned to totally understand the concept of energy.  

However, knowledge the 2 main forms of energy that pass through not only daily life, but also the main point of physics transparent the universe, is a great starting point and set the structure for any type of deeper dives into the nature of power itself.  

There are just two points that absolutely need to be remembered: stationary objects with stored power have potential and also moving objects space kinetic.
