Question

Differentiate between kinetic energy and potential energy.
Write the formula to calculate
Kinetic energy and potential energy of a body.

Answer 1

Answer:

kinetic energy= 1/2 mv²

potential energy= mgh

Answer 2

Answer:

Kinetic energy is the energy possessed by moving objects only, while potential energy is the energy due to the position or configuration change of the object.

Explanation:

Mechanical energy is a kind of energy that is associated with the motion or position of an object. Kinetic energy and potential energy are the two different classifications of mechanical energy.

If an object of mass m moves with a velocity v then it is said to possess kinetic energy and it is given by the equation:

K.E = (mv²) / 2

If an object of mass m is raised at a height h above the ground level or if its configuration is changed, then the object is said to possess potential energy and it is given by the equation:

P.E = mgh

Where g is the acceleration due to gravity.
