Q:

# What are some similarities between kinetic and potential energy?

A:

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.

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.

• A:

Gravitational potential energy depends on the mass of the object, acceleration because of gravity and the height of the object from a zero position, which is typically the ground or surface where the object is resting. This is because potential energy is the amount of energy stored in an object due to its position and represents the potential for a force, such as gravity, to do work on the object.

Elastic potential energy is the energy stored from an elastic object being stretched or compressed. It equals the amount of work that was done to stretch the object. The equation for elastic potential energy is PE=1/2kx2, where "PE" is the potential energy, "k" is a spring constant and "x" is the displacement.

Potential energy is the stored energy of an object that has the potential to change to a different form of energy to do work. The types of potential energy are gravitational, elastic, chemical, electric and nuclear.
