Motion

By Newton’s second law of motion, the force acting on a body = m a, where m = mass of the body and a =…

(i) Impulsive Force An impulsive force is a very great force acting for a very short time on a body, so that the change in…

Momentum of Body is observed experimentally that the force required to stop a moving object depends on two factors: (i) mass of the body and (ii)…

Consider a body projected from a point O on the surface of the Earth with an initial velocity u at an angle 8 with the…

Let consider an object thrown horizontally with a velocity u from a point A. which is at a height h from the horizontal plane OX…

A body thrown with some initial velocity and then allowed to move under the action of gravity alone, is known as a projectile. If we…

Though friction has many disadvantages it is considered as a necessary evil. What causes it? We cannot do anything without the force of friction. If…

Friction is inextricably related to our daily lives. Friction can be increased in necessity; again friction can be decreased too in necessity. How friction can…

Friction has an enormous influence on the motion of an object. Friction is a kind of resistive force which slows down the motion of a…

Generally there are four types of friction. Static friction Sliding friction Rolling friction Fluid friction Static: Static friction is the friction between two surfaces that…
