Law of Motion

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.…

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 theorem states that “the moment of inertia of a plane lamina about an axis perpendicular to its plane is equal to the sum of the moments…
