numerical problems on law of motion

01. An object of mass 5 kg is lifted up through a distance of 2 meter. What is the work done? Solution: W = F x s Also, force acting on the object is F = mg [Newton's second law of motion] Mass of the object (m) = 5 kg Distance moved = 2m Therefore, Work done = F x s ..

Whenever we push or pull an object, we do so by means of a force. Force is an interaction between two bodies which causes acceleration, or simply, motion..

We shall now study about the exact relation between the force applied and the motion of the object on which the force is applied. This was studied by Sir Issac Newton. He gave the three basic laws of motion concerning objects in motion..

Newton's second law of motion states that rate of change of momentum is directly proportional to applied force and takes place in the same direction as the applied for..

Newton's Third Law of Motion - Suppose you are watching the lift off of a space-shuttle. You hear a deafening roar and see burning gases shooting from the exhaust vents of the rockets. At that moment, the space shuttle system moves slowly upward. You can infer that the force for..

Newton's Second Law of Motion - Earlier we have mentioned that application of force can change the velocity of the moving object. Let us suppose that a body of mass 'm' is moving with a velocity 'u'. When a force F is applied on the body for 't' seconds, the velocity changes fro..

Every body continues in its state of rest or of uniform motion in a straight line until and unless acted upon by an external forc..
