1
Q

What is linear momentum?

A

mass x velocity

2
Q

What is Newton’s first law of motion?

A

An object will remain at rest or continue to move at a constant velocity unless acted on by a resultant force

3
Q

What is Newton’s third law of motion?

A

When two objects interact, they exert equal and opposite forces on eachother

4
Q

What is Newton’s second law of motion?

A

The resultant force acting on an object is directly proportional to the rate of change of momentum and is in the same direction

5
Q

What is the principle of the conservation of momentum?

A

Total momentum of a closed system remains the same before and after a collision

6
Q

What is an elastic collision?

A

A collision in which kinetic energy is conserved
