Momentum and Impulse Flashcards
1
Q
Momentum depends on?
A
Mass and Velocity
2
Q
Momentum is conserved if
A
no external forces act
3
Q
Elastic Collisions, what is conserved
A
momentum and kinetic energy
4
Q
Inelastic collision, what is conserved
A
momentum (some ke is converted)
5
Q
Newtons 2nd Law
A
The rate of change of momentum of an object is directly proportional to the resultant force which acts on it, F=MA
6
Q
Impulse=
A
Change of momentum
7
Q
Area under force time graph=
A
Impulse
8
Q
Force of an impact can be reduced by
A
increasing the time of impact
