Momentum (y) = mass x velocity
Vector Quantity
Impulse Momentum:
= F(change in time) = mv(final) - mv(initial)
= change in momentum
- units = Nm or kg(m/s)
Greater change in momentum requires more force or more time
if you apply force on an object, it will gain some momentum
if an object loses momentum, it must be imparting some force to something else over some time period
Longer contact means more momentum imparted
Example: Miyuki swings the bat fully so that the force imparted is greater instead of stopping when the ball touches the bat
When objects collide, total momentum is conserved
