Impulse and Momentum

The impulse experienced by a body is equal to the change in its__________.

• velocity

• momentum

• kinetic energy

• potential energy

It is the rate of change of the velocity of an object with time.

Why is massive car difficult to stop? It’s because it possesses a____________.

• lesser inertia in motion which depends on object’s mass and force

• greater inertia in motion which depends on object’s mass and force

• lesser inertia in motion which depends on object’s mass and velocity

• greater inertia in motion which depends on object’s mass and velocity
