When two objects collide what happens to the impulses received by them?
What theorem is this?
The impulses are equal and opposite
Newton’s third law
What is meant by a perfectly Inelastic collision?
What happens to Kinetic Energy in a perfectly Inelastic collision?
Two objects collide and move as one
It decreases by the maximum possible amount
When two objects are at rest then push each other apart, what happens to the momentum
P=0 Ns
What happens to the total momentum if a third object is involved?
Why don’t we calculate friction?
Momentum increases or decreases by the amount of the third object?
Momentum is not constant
If two balls collide what happens to the momentum before and after?
What is the momentum lost by the second ball?
The momentum is constant
It is equal to the momentum gained by the first ball
How do you reduce the force involved in a collision?
What is this theorem called?
Extend the time
The impulse momentum theorem
How do you change the momentum?
Deliver an impulse
