1
Q
Momentum =
A
Mass x velocity
2
Q
Momentum is always what?
A
Conserved, assuming no external forces act.
3
Q
What are elastic collisions?
A
Ones where KE is conserved.
4
Q
What are inelastic collisions?
A
Ones where KE is not conserved.
5
Q
F =
A
Change in momentum / time
6
Q
What is rate of change of momentum directly proportional to?
A
The resultant force which acts on the object.
7
Q
Impulse =
A
Change in momentum
8
Q
