Question

Motion is a common and most important phenomenon in nature. In the case of macroscopic bodies, it is easy observable. But if we go down to atomic or even nuclear level motion is not observable but is very much there. Motion may be as simple as throwing a ball up into the air. On the other hand motion may be as complicated as the launching of a communication satellite into its Orbit. Behind every motion there is an effect known as force. Forces are majorly divided into two types. i)Balanced forces ii)Unbalanced forces. Sir Isaac Newton studied the motion of bodies and established some relation between force and motion. He formulated three laws to the motion of bodies. The amount of motion contained by A body moving body is known as momentum. Newton's second law of motion deals with rate of change of Linear Momentum. It is known that when two bodies or more interact with each other then their total linear momentum remains conserved or constant provided that no external unbalanced forces act on them. This is known as Law of Conservation of Linear Momentum. This law is applicable even in those situations that Newton's third law of motion does not hold good. 16.a) A force of 200 N is required to push a car of mass 500 kg slowly at constant speed on a leveled road. If a force of 500 N is applied, the acceleration of car will be:​

Answer 1

Explanation:

mass = 500 kg

force =500 N

acceleration = force / Mass

= 500/500

= 1 acceleration
