1
Q
What is an elastic collision?
A
When before collision total KE of objects = total KE after collision
2
Q
What is impulse?
A
A measure of change in momentum
3
Q
What does the area underneath a force time graph equal?
A
Impulse
4
Q
What is Newton’s first law?
A
An object will remain in a state of rest or constant velocity unless acted upon by an external force
5
Q
What is Newton’s second law?
A
The net force acting on an object is proportional to the rate of change of momentum
6
Q
What is Newton’s third law?
A
When two objects interact, they exert an equal and opposite force on each other
