Question

What is kinetic energy and potential energy??

Answer 1

Kinetic energy of an object is defined as the energy which it possesses by virtue of its motion , and is measured by the amount of work that the object can do against an opposing force before it comes to rest .

Example of kinetic energy :
A bullet fired from a gun can pierce through a target on account of kinetic energy of the bullet.

On the other hand , The energy possessed by an object by virtue of its position or configuration is called its potential energy . It is measured by work that the object can do in passing from its present position or configuration to some standard position or configuration (known as zero position or zero configuration) .
Example of potential energy : When a stretched bow is released, the arrow goes forward with a large velocity on account of potential energy of the stretched bow.
