A
Momentum = Mass x Velocity
2
Q
DOES MOMENTUM HAVE DIRECTION?
A

Q
WHAT IS THE EQUATION FOR FORCE?
A
Force = Change in momentum / Time

Q
WHAT DOES THE LAW OF CONSERVATION OF MOMENTUM STATE?
A
The total momentum before and after a collision are equal, provided that no external forces are acting on the objects
