We may, in fact, ur foot while doing so! ity 9.2, instead of a The first law of motion indicates that when an unbalanced external force acts on an of impor property That is, (9.1) mass and its velocity. One suc called momentum was introduced by Newton. The momentum. p of an object is defined as the product of its mass, m and velocity, v. (p=mv | Momentum has both direction and magnitude. Its direction is the same as that of velocity,. v. The SI unit of momentum is kilogram-metre per second (kg m s). Since the application of an unbalanced force brings a change in the velocity of the object, it is therefore clear that a force also produces a change of momentum. Let us consider a situation in which a car with a dead battery is to be pushed along a straight road to give it a speed of 1 m s¹, which is sufficient to start its engine. If one or two persons give a sudden push (unbalanced force) to it, it hardly starts. But a continuous push over some time results in a gradual acceleration of the car to this speed. It means that the change of momentum of the car is not only determined by the magnitude of the force but also by the time during which the force is exerted. It may then also be concluded that the force necessary to FORCE AND LAWS OF MOTION The rate of cha Or. the appli Here which is quantit The Sl and m chose becom defin acco mas TH
