the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.
SI unit: joule (J)
Common symbols: KE, Ek, or T
Derivations from other quantities: Ek = ½mv2; Ek = Et+Er
formula is k.E=mga
AND
potential energy is the energy that is stored in an object due to its position relative to some zero position. An object possesses gravitational potential energy if it is positioned at a height above (or below) the zero height.
formula is P.E =mgh

here's your answer:-
________________________________________________________________________
◆KINETIC ENERGY:- the energy possessed by a body by the virtue of its state of motion is known as kinetic energy.
>>examples- a moving car, a moving boy, a moving fan, a fired bullet ....etc. (include any examples which constitute something in motion)
>>formula- 1/2 mv^2 ( where m= mass of body, v= velocity of the body).
>>symbol- kinetic energy is usually denoted by the symbol 'K'.
◆POTENTIAL ENERGY:- the energy possessed by a body by virtue of its changed position from a reference level is known as potential energy.
>>examples- water stored in a tank, a book kept at the top of a shelf , a toy placed at the top of building( the water, or book or toy possess some potential when they are placed at a reference level).
>>formula- mgh ( where m=mass, g= gravity {approximately equal to 9.8 m/s^2}, h= height if The body).
>>symbol- the potential energy of a body is usually denoted by 'U'.
●S.I. unit of both of them is Joule (J).
