MOMENTUM

What is momentum???????

Momentum is defined as the mass of an object multiplied by its velocity.

momentum= mass x velocity

p= mv

* The unit of momentum kgm/s

* If we donate the direction to the right as positive momentum, an object moving to the right posseses a positive momentum, while another object moving to the left has a negative momentum.

EXAMPLE: A ball of mass of 0.8kg strikes a wall at a velocity of 10m/s and rebounds at 6m/s. What is the momentum, before striking the wall and after the rebound?

Solution :

Taking the direction to the right as positive.

Momentum of the ball before striking the wall,

P1=mv

=0.8 x 10

=8kg m/s

Momentum of the ball after rebound

P2=mv

=0.8 x (-6)

=-4.8kg m/s
