Kinetic and potential energy are both typically ascribed as forms of mechanical energy and can be interchangeably converted. Potential energy can be converted into kinetic energy and vice versa, but the change is always accompanied by the dissipation of some energy as heat.Continue Reading
Kinetic energy is the energy of a body due to movement, while potential energy is the energy of a body by virtue of its position or state. The kinetic energy of a body depends on its frame of reference. A body matching velocity with its reference frame is stationary in that reference frame but moving in another reference frame. In the frame where the body appears stationary, its kinetic energy is zero. Kinetic energy is proportional to square the velocity and the mass according to the Newtonian laws of motion and must be assigned real, positive values, as neither real mass nor velocity squared can be negative. As the velocity increases at one rate, the kinetic energy increases at square this rate.
Potential energy also depends on the reference frame. Gravitational potential energy is directly proportional to height. Depending on the reference level from which the height is measured, potential energy can be positive, negative or zero.Learn more about Motion & Mechanics
Potential energy that depends on height is called gravitational potential energy. If an object is in a vertical position, then gravity is acting on it as a downward pull. Although the amount of gravitational potential energy an object has depends on the height, the object's mass is another influencing factor.Full Answer >
Kinetic, potential, thermal, chemical, electrical, electrochemical, electromagnetic and nuclear energy are the different forms of energy. Each energy form measures the ability of an object to do work on another object. Each energy form is a way that an object possesses energy.Full Answer >
As the height of an object triples, the potential energy of said object also triples. Potential energy is directly related to an object’s height and increases or decreases linearly as the height of the object increases or decreases.Full Answer >
Examples of elastic potential energy include a rubber band, spring, bouncing ball, catapult, bungee cord, bow string and trampoline. Elastic potential energy is stored in these objects when they are pulled, stretched or compressed. This energy becomes kinetic energy when these objects return to their original shape. For instance, a compressed spring has elastic potential energy until the coils return to their original alignment and push other objects away.Full Answer >
