Which of these statements are correct?
Tick 2 boxes.
Momentum is always conserved
Kinetic energy is always conserved
Momentum is sometimes conserved
Kinetic energy is sometimes conserved
Which circumstance is kinetic energy NOT conserved?
Perfectly elastic collisions
Inelastic collisions
Collisions where the momentum changes
What is the formula for momentum?
momentum = 1/2 x mass x velocity2
momentum = mass x velocity
momentum = mass / velocity
momentum = mass x velocity2

The faster one
The slower one
Their momentum will be the same
Two objects have the same speed but different masses. Which will have the highest momentum?
The more massive one
The less massive one
Their momentum will be the same
