appreciate that the area under a forceâtime graph is the change in momentum, which is also called impulse

apply the law of conservation of momentum in collisions and explosions
4.3
distinguish between elastic and inelastic collisions

apply momentum conservation to 2D collisions
4.5
REFLECTION
Can you find the change in the momentum of an object? Can you calculate the total momentum of a system? Can you apply Newtonâs second law in terms of momentum? Can you solve problems when mass is changing? Do you understand when momentum is conserved? Do you understand the concept of impulse and do you know what impulse is equal to? Do you know what information a graph of force versus time gives?
