# SSC MCQ Question Ans. Let Us Know the Force

SSC MCQ Question Ans. Let Us Know the Force. We are pulling or pushing something in every moment. To change the state of motion of an object we pull or push, that is, we apply force. An object at the state of rest can be brought in the state of motion again an object in motion can be changed the direction and magnitude of motion even its motion can be stopped by applying force. We will discuss in this chapter about the inertia, the force, the effect of force on a body at rest or in motion, Newton’s first law of motion, nature of force, measurement of force, Newton’s second law of motion, action-reaction of forces and Newton’s third law of motion.

If anyone of your friends wants to displace you by keeping his hand on your body then you will say that he is pushing you. If we want to displace anything then we push it. If we want to bring anything near to us we pull it. This push or pull on a body by another body is the force. Whenever we push or pull, raise or bend, twist or tear, expand or compress anything, then we actually apply force. Scientist Sir Isaac Newton in 1667 published three laws making relation among force, mass, inertia, and motion of objects. These three laws are known as Newton’s laws of motion.
