Moving objects have Moving objects have momentum!momentum!
Momentum depends on Momentum depends on both velocity AND mass!both velocity AND mass!
An object’s momentum An object’s momentum is in the same is in the same
direction as its velocitydirection as its velocity
Momentum = Momentum = mass x velocitymass x velocity
Momentum is often represented by the Momentum is often represented by the letter “p” in equations i.e. p=mv means letter “p” in equations i.e. p=mv means
momentum=mass x velocitymomentum=mass x velocity
Law of conservation of Law of conservation of momentummomentum
The total amount of momentum in The total amount of momentum in a system is conserved. a system is conserved.
This means that momentum, This means that momentum, like energy and mass, cannot like energy and mass, cannot be created or destroyed-but be created or destroyed-but it can be transferred to it can be transferred to another object, though!!another object, though!!
Marcus’ most excellent example:Marcus’ most excellent example:
If a baseball team is winning, and If a baseball team is winning, and suddenly the other team makes a suddenly the other team makes a comeback, the momentum has comeback, the momentum has SHIFTED to the other team, but the SHIFTED to the other team, but the momentum was not destroyed, nor momentum was not destroyed, nor was any NEW momentum created!! was any NEW momentum created!!
