P2.2.6 - Momentum Flashcards
1
Q
What does momentum depend upon?
A
Mass and velocity
2
Q
Is momentum a vector or scalar?
A
Vector
3
Q
What is the calculation for momentum?
A
Mass * velocity
4
Q
What is the law of conservation of momentum?
A
In any collision momentum is conserved, so the momentum before is equal to the momentum after
5
Q
In an elastic collision, how much energy is transferred to other stores?
A
None
6
Q
Why do snooker balls not always maintain the same speed when they collide?
A
Some of the energy is transferred to a thermal store by sound
7
Q
What is an inelastic collision?
A
A collision where energy is transferred to other stores
