Acceleration

falling stone gravitation

Gravitation: Why does a stone fall towards the earth but the opposite is not observed?

Gravitation and a Falling Stone As said by this law of universal gravitation every object in this universe is attracting every other object towards it. This force of gravitational attraction between any two objects in the universe is inversely proportional to the square of the distance between the objects. This force is again directly proportional

GRAVITATION - FREE FALL

Free fall, Acceleration due to Gravity and Kinetic Energy

Weight of any object is a force applied on the object by earth’s gravitational pull towards the center of the earth. We know the equation of a force = mass * acceleration. i.e.      F=m*a…….(1) When we talk of weight force then the equation becomes like this: Weight(W)= mass * acceleration due to gravity
