Define momentum of a body.

The momentum of a body

Linear momentum of a body is defined as….. .

When the momentum of a body a doubled, the kinetic energy is

State the relation between the momentum of a body and the force acting on it.

Regarding linear momentum of a body (a) It is a measure of quantity of motion contained by the body (b) Change in momentum is the measure of impulse (c ) Impulse and acceleration act in opposite direction to the change im momentum (d) In the case of uniform circular motion the linear momentum is conserved .

The linear momentum of a body can change only in the direction of applied force Comment .
