4.5.7 Momentum

Calculate momentum by recalling and applying the equation: [ p = mv ]
Explain and apply the idea that, in a closed system, the total momentum before an event is equal to the total momentum after the event
Describe examples of momentum in a collision
Complete conservation of momentum calculations involving two objects
Explain that when a force acts on an object that is moving, or able to move, a change in momentum occurs
Calculate a force applied to an object, or the change in momentum it causes, by applying but not recalling the equation: [ F = m Δv / Δt ]
Explain that an increased force delivers an increased rate of change of momentum
Apply the idea of rate of change of momentum to explain safety features such as air bags, seat belts, helmets and cushioned surfaces
