Question

what is potential energy and kinetic energy. Explain in brief with examples.

Answer 1

The energy possed by a body due to its motion is called kinitic energy
eg.... When athletes run.
the energy possed by a body due to change in shape,size is called potential energy.
eg.... when we streach the rubber.

hope it will help u .mark it plese

Answer 2

Mechanical Energy = Potential Energy + Kinetic Energy



⇒Potential Energy :-
Potential Energy is the Energy possessed by a body by virtue of its height or by virtue of its strained configuration
Potential Energy = mgh , m = mass , g = acceleration due to gravity , h = height

Can you list some examples ??

Here are some examples ....

A stretched rubber band , a winded spring , Water stored in a dam , Bow and Arrow.

⇒Kinetic Energy:-
Energy possessed by a body by virtue of its motion.
All moving bodies possess Kinetic Energy
Kinetic Energy = 1/2 mv² , m = mass , v = velocity

Here are some examples .....

Running athlete , racing car , coconut falling from a tree etc ....
