Working of Rocket and Jet Plane in terms of Newton’s Third Law

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

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......

Newton’s Second Law of Motion

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......

Newton’s First Law of Motion

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......

Harmonic Motion: Mathematical Solution

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......

Uniform Circular Motion: Mathematical Solution

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,......

What is Uniform Circular Motion?

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......

Motion in 2 Dimension: Mathematical Examples

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......

Motion in 1 Dimension: Mathematical Examples

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

What are the fundamental forces?

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

What are inertia of rest and inertia of motion?

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......

What do you mean by friction?

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......
