What is spring??? |
|
Answer» A spring is a mechanical device that produces a restoring force when stretched or compressed. The suitable definition is---- the body which have negligible mass and can have capabilities to store force or energy and both is called spring.... If elasticity is matter then the plastic must be spring.... Spring is defined as the present elasticity |

A light body and a heavy body have the same kinetic energy. Which one will have greater momentum |
|
Answer» K.E. =P^2/2M where p=momentum and M =mass of the bodyThis gives P^2=K.E.×2Mi.e. P=√K.E×2M or P is directly proportional to √2MSince K.E. is the same for both the bodies, heavier body will have greater momentum. Heavy body due to greater mass |
