The more mass an object has, the more kinetic energy it has. According to this equation, what effects K. Velocity Potential Energy :. Potential energy is called the energy of position. Energy that is dependant on height is called gravitational potential energy. The formula for potential energy is:.
Weight mass x gravity determines the amount of potential energy. Is there potential energy in the 5 forms of energy? Yes, potential energy can be found in fossil fuels, within the foods you eat, and the batteries that you use. Conservation of Energy :.
Chemical energy possessed by a substance due to the potential it has to undergo a chemical change by taking part in a chemical reaction is chemical potential energy of the substance. When fuel is used, for example, chemical energy stored in fuel is converted to produce heat. Electrical potential energy — energy possessed by an object by virtue of its electric charge is electrical potential energy. There are two types — electrostatic potential energy and electrodynamic potential energy or magnetic potential energy.
Nuclear potential energy — potential energy possessed by particles neutrons, protons inside an atomic nucleus is nuclear potential energy. For example, hydrogen fusion in the sun converts potential energy stored in solar matter into light energy. Applications The roller coaster in an amusement park begins with the conversion of kinetic energy into gravitational potential energy.
The gravitational potential energy keeps planets in orbit around the sun. Projectiles are thrown by a trebuchet making use of gravitational potential energy. In spacecrafts, chemical energy is used for take off after which the kinetic energy is increased to reach orbital velocity.
Kinetic energy gained remains constant while in orbit. Kinetic energy given to cue a ball in a game of billiards is transferred to other balls through collisions.

In Science, however, energy is defined as the capacity to do work. This definition is still not very satisfactory to us, but it is difficult to define energy with great precision. Energy exists in many forms. Some of them are Potential Energy, Kinetic Energy, Chemical Energy, Nuclear Energy, Electrical Energy etc: Also, it is pertinent to note that there are other forms of energy like heat and work in the process of transfer from one body to another body.
The unit of energy is Joules. It is a bit difficult to define energy in very precise terms because it is an abstract notion and not something tangible. Energy is generally carried by something, usually in the form of movement.
When objects move or remain in a position, they have energy which has different names. Though energy exists in various forms as mentioned earlier, it is important to understand that energy remains conserved always. When a form of energy is converted from one form to another during any process, the overall quantity of energy remains the same; there is no loss or gain.
This is what is called as conservation of energy. Our discussion here will focus on only two of the forms of energy — Potential Energy and Kinetic Energy. Let us now go into each of these separately to understand them first. An energy that is stored in an object and not moving, but which has the potential to move is called Potential Energy. Potential Energy or PE as we can call is the energy possessed by an object because of its position relative to another body.
The PE could also be the energy in a body due to its internal stress if any or the electrical charges in a body. One of the most common forms of PE is the gravitational potential energy. The amount of PE, in this case, depends on the mass of the body. This is the energy required to move a body against the force of gravitation of the earth. A spring when extended has energy in it waiting to come back to its original position. This also has enough potential energy. The term potential energy was first coined by a great physicist William Rankine in the 18 th century.
Potential energy is always determined based on the position of a body and not based on its trajectory of movement. Some of the important factors that impact PE are its mass, its height relative to another object, and strength of the gravitational field. Imagine a book or a ball of iron resting on a table at a height of 2 meters from the ground.
