Differentiate between kinetic and potential energy
Answers
Potential Energy
Potential energy is the energy stored within an object. An illustration of potential energy is stretching a rubber band. Stretching the rubber band builds up energy, preparing it for motion. This is referred to as elastic potential energy. There is also gravitational potential energy. This type of potential energy is the result of the height of an object and gravitational pull. Potential energy is stored within a mass or object until it begins to move.
Kinetic Energy
Kinetic energy is the energy of an object in motion. Potential energy is converted to kinetic energy when the object begins to move. There are three types of kinetic energy: vibrational, rotational and translational. Each type of kinetic energy is named according to the type of movement the object experiences or performs. Vibrational kinetic energy is the energy that results when an object vibrates. Rotational occurs when an object rotates or turns. Translational kinetic energy refers to an object moving from one location to another.
Kinetic energy is represented as the state of energy of a body because of its motion. Its equation is given as:
K.E. = ½ (m * v^2)
where
m = mass of the body in kgs
v = velocity
Potential energy is represented as the state of energy of a body because of its rest. Its equation is given as:
P.E. = mgh
where
m = mass of the body in kgs
g = acceleration due to gravity (9.8 m/s^2)
h = height in meters
