$A$ stone is dropped from a cliff. Its speed after it has fallen $100 \,m$ is: (in $, m s^{-1}$)

The factors associated with the motion of an object are: Force,Velocity,Acceleration,and Momentum. Out of these four factors,which one remains constant for all bodies—large or small—undergoing a free fall?

$A$ soft drink bottle is dropped by a waiter from the top of a hotel whose height is $100 \, m$. It takes $T$ seconds to reach the ground. Where will it be at $T/2$ seconds?

An apple falls from a tree because of gravitational attraction between the earth and the apple. If $F_1$ is the magnitude of force exerted by the earth on the apple and $F_2$ is the magnitude of force exerted by the apple on the earth,then:

The acceleration due to gravity on the surface of the Earth is:

Why is the value of $g$ more at the poles than at the equator?
