When two bodies, a heavy one and a light one, are acted upon by the same force for the same time, the light body attains a higher velocity (or higher speed) than the heavy one. But the momentum gained by both the bodies is the same. The link between force and momentum is expressed in

NEWTON’S LAWS OF MOTION Newton has given three laws to describe the motion of bodies. These laws are known as Newton’s laws of motion. The Newton’s laws of motion give a precise definition of force and establish a relationship between the force applied on a body and the state of motion acquired by it. We

The three equations of motion : v = u + at ; s = ut +1/2 at² and v² = u² +2as can be derived with the help of graphs as described below. 1. To Derive v = u + at by Graphical Method Consider the velocity-time graph of a body shown in Figure 43.

Forces are of two types : Balanced forces and Unbalanced forces. We will now discuss balanced and unbalanced forces in detail, OnePlus by one. Let us start with balanced forces. Balanced forces If the resultant of all the forces acting on a body is zero, the forces are called balanced forces. A body under the

A body has a uniform motion if it travels equal distances in equal intervals of time , no matter how small these time intervals may be . For example , a car running at a constant speed of say , 10 metres per second , will cover equal distances of 10 metres , every second

There are three equations for the motion of those bodies which travel with a uniform acceleration . These equations give relationship between initial velocity , final velocity , time taken , acceleration and distance travelled by the bodies . We will study these equations one by one . 1. First Equation of Motion The first
