What is the momentum equation?
momentum (kg m/s) = mass (kg) × velocity (m/s)
1 of 5
Can you name 2 things that momentum has and describe them?
magnitude - an amount because it depends on the object’s mass
2 of 5
What always happenes to momentum?
it is always conserved, this csn be used to work out the mass, velocity or momentum of an object in an explosion or collision.

Can you use momentum to describe safety features on a car?
seatbelts, they can stretch to increase the time taken for the body's momentum to reach zero. airbags, increase the time taken for the head's momentum to reach zero.

A bullet with a mass of 0.03 kg leaves a gun at 1000 m/s. If the gun’s mass is 1.5 kg, what is the velocity of the recoil on the gun?
momentum of bullet = mass × velocity, = 0.03 kg × 1,000 m/s. = 30 kg m/s
