### 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.The......

### 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 nature is called fundamental forces. In other words, those forces which are fundamental and do not originate from......

### 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......
