Explain 'Relative velocity'.

Explain the term : Relative velocity.

Explain critical velocity for ideal fluid.

A boat is moving with velocity of 3 hat i+ 4hat j in river and water is moving with a velocity of 3 hat i- 4hat j ith respect to ground. Relative velocity of boat with respect to water is

The ratio of relative velocity of separation after collision to the relative velocity of approach before collision between two colliding bodies is ____________.

An aeroplane A, is travelling in a straight line with a velocity of 300 km/ hr with respect to Earth . Another aeroplane B, is travelling in the opposite direction with a velocity of 350 km/hr with respect to Earth. What is the relative velocity of A with respect to B? What should be the velocity of a third aeroplane C moving parallel to A, relative to the Earth if it has a relative velocity of 100 km/hr with respect to A?

With the help of proper diagrams Explain Projection of velocity :
