Momentum
Physical quantity that describes the quantity of motion in a body is called momentum. The momentum of a moving body is defined
Elastic after effect
When a elastic body is stretched and applied deforming force is removed then the body is expected to return to its original configuration instantaneously. But
Variation of ‘g’ due to depth
Let us consider the earth to be spherical mass of ‘M’ and radius ‘R’. A body of mass ‘m’ is placed initially

Variation of g due to shape of the earth
The shape of the earth is bulged at the equator and flat at the poles. This means earth has
