Angular momentum
Videos
Angular momentum is the rotational analog of linear momentum. It is an important physical quantity because it is a conserved quantity – the total angular momentum of an isolated system remains constan
This gyroscope remains upright while spinning owing to the conservation of its angular momentum.
A figure skater in a spin uses conservation of angular momentum – decreasing her moment of inertia by drawing in her arms and legs increases her rotational speed.
Motion

In physics, motion is the change in position of an object or fluid with respect to a reference frame over a given time. Motion is mathematically described in terms of vector quantities such as displac
A car is moving in high speed during a championship, with respect to the ground the position is changing according to time hence the car is in relative motion
