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 =

Work done by a force

Work done by a Force In Physics Work is done by a force applied only if the object on which the force is applied makes a displacement. Without this displacement, work done is zero irrespective the force you have applied. Work done by a force depends on the 3 parameters: (a) the force applied (b)
