Find the ratio of Distance covered to the Displacement covered by the body moving along semi-circular path of radius r:

Newton’s second law of motion:

Newton’s first law of motion is:

The law which defines force is:

Mass measures amount of ---------- in a body:

A man sitting in a train in a motion is facing the engine. He tosses a coin up, the coin falls behind him. The train is moving:

A body A has a mass 5 kg. Now this is broken into two pieces. Is inertia of the two pieces combined more than the inertia of A when it was not broken:

Newton’s second law of motion is

When a force 1N acts on mass of 1kg, which is able to move freely, the object moves with a/an:

A body of mass M strikes against wall with a velocity’ v’ and rebounds with the same velocity.
Its change in momentum is:

A body of mass 5 kg undergoes a change in speed from 20 m/s to0.20 m/s. The momentum:

When a bullet is fired from a gun. The gun recoils to:
