1.6 Momentum

Question 1

Formula for momentum

Answer 1

p = mv
Momentum = mass x velocity

Question 2

What is the principle of the conservation of momentum?

Answer 2

Total momentum before a collision = total momentum after a collision

Question 3

What is the formula for impulse?

Answer 3

Impulse = force x change in time = change in momentum = final momentum - initial momentum
IN WORKING: impulse = mv - mu (final momentum - initial momentum)

Question 4

Formula to define force as rate of change of momentum

Answer 4
