-the mass of the ball
-the velocity of the ball
  • Momentum is the ____________ of an object

The incredible Hulk plans to stop a rolling
boulder from crushing innocent children. If the
boulder has a mass of 100 kg and is moving
towards him with a velocity of 6 m/s (north) than
what will be the momentum of the boulder that the
Hulk must overcome?

Conservation of Momentum
The total momentum of any given system will
remain constant unless acted upon by an external
force. or The momentum before a collision is
equal to the momentum after a collision.
Example You are rolling a bowling ball into
pins. Momentum of ball (before) MV Momentum
of pins (before) m0 Momentum of ball (after)
Mv Momentum of pins (after) mV Conservation
of momentum mv(ball )before mv(pins)before
mv(ball)after mv(pins)after
