The propulsion of a rocket is one of the most interesting examples of Newton’s third law of motion and the law of conservation of momentum.The......

Newton’s Third Law of Motion states that ‘To every action there is an equal and opposite reaction’. It is a common observation that when we......

The second law states that the rate of change of momentum of a body, is directly proportional to the force applied and this change in......

The first law states that every body continues in its state of rest or of uniform motion along a straight line unless it is compelled......

Example 1: At time t = 0, the displacement is x = 2.72 m, the velocity is v = —2.54 m/s, and the acceleration is......

Example 1: An object goes around a vertical circular track, as shown. Find the minimum speed of the object near the top of the loop,......

In uniform circular motion, the object travels with constant speed v along a fixed circular trajectory with radius r. The speed and radius determine the......

Example 1: A projectile is launched with V0 = 19.2 m/s at angle θ0 = 38.7°. a) Does the projectile `clear’ a 3.0 m- high......

Example 1: Emmy starts at time t = 0 and drives along a straight path: she starts at point A, drives straight to point B,......

The force whose actions-reactions are seen in nature is called fundamental forces. In other words, those forces which are fundamental and do not originate from......

The inertia of a body is defined as that property of it, which tends to resist a change in its state of rest or of......

Whenever a body in contact with a second one, moves or tends to move, forces opposing the motion come into play. They are tangential to......
