A
Mass and Velocity
2
Q
What is the equation for momentum?
A
Momentum (kg m/s^2)
Mass(kg) x Velocity(m/s)
3
Q
What is the law of conservation of momentum?
A
The momentum before a collision is equal to the momentum after
4
Q
What happens in a elastic collision?
A
No energy is transferred to other stores
The energy stays the same
5
Q
Is a real collision always perfectly elastic?
A
No some energy is transferred to the thermal store by sound
6
Q
What is an inelastic collision?
A
Some energy is transferred to other stores
