1. The energy possessed by any moving object is known as kinetic energy.E.g - Flowing water, moving car etc.
=================================
2.The energy possessed by any object due to its orientation in 3D space is known as potential energy.
potential energy can be due to change in height, known as gravitational potential energy or due to elasticity known as elastic potential energy etc.
E.g - An object kept at particular height, A spring been compressed etc

KINETIC ENERGYIt is the energy possessed by an object due to its motion.
SI unit ---> Joule (J)
The kinetic energy increases with increasing velocity and increasing mass.
KE = 1/2 mv^2, where m = mass of the object, v = velocity of the object
Example --> A bullet fired from a gun pierces a target.
POTENTIAL ENERGY
The energy possessed by a body due to change in its position or shape is called potential energy.
SI unit ---> Joule (J)
When height increases potential energy also increases.
P.E = mgh
where m = mass of the object
g = acceleration due to gravity
h = height at the which the object is situated
Example ----> Water stored in a dam
