Motion and Rest - Imagine yourself sitting in a seat while travelling in a moving train. You observe no change in position with respect to the window. There is change of scene when you view through the window. The change of scene indicates that the train is movi..

A vegetable vendor applies force to push the cart, a driver applies force either to stop the car or to change the speed or direction of motion and a football player kicks the ball to set it in motion. In all the above examples, the force applied on a body can bring about the fol..

Let 'u' be the initial velocity of an object and a be the acceleration produced in the body. The distance travelled 'S' in time 't' is given by the area enclosed by the v - t graph. Graphical Derivation of Third Equation S = area of the trapezium OABD. ..

Imagine you are travelling in a moving train. Do you observe any change in your position with respect to your co-passengers? Is there any change of scene you view through the window? The change of scene indicates that the train is moving. That is, an object is said to be in motion i..

Consider a simple system in which two blocks are connected by a string which passes over a light, frictionless pulley as shown below. M 1 a = T-m 1 g M 2 a = m 2 g-T a (m 1 + m 2 ) = (m 2 - m 1 )..

Consider an object moving with a uniform velocity u in a straight line. Let it be given a uniform acceleration a at time t = 0 when its initial velocity is u. As a result of the acceleration, its velocity increases to v (final velocity) in time t and s is the distance covered by the object in time..

As the initial velocity, final velocity, distance travelled, acceleration and time are related and are expressed as equations of motion in linear motion; one can derive equations for rotational motion also. If w 0 is the initial angular velocity of a rotating rigid bod..
