1.10 Momentum

Question 1

What is the formula for momentum?

Answer 1

p = m * v

p = momentum (kg m/s)
m = mass (kg)
v = velocity (m/s)

Question 2

What is a closed system?

Answer 2

A scenario which has no external forces

Question 3

What is the conservation of momentum?

Answer 3

In a closed system, the total momentum before an event is the same as the total momentum after the event

Question 4

What is the formula for force in terms of change in momentum?

Answer 4

F = (mv - mu) / t

F = force (N)
mv = final momentum (kg m/s)
mu = initial momentum (kg m/s)
t = time (s)

Question 5

What does the momentum of an object depend on?

Answer 5

It’s mass and velocity
