What's the average value for the acceleration due to gravity on earth?
9.81 m/s^2 but we round it up to ten
What's air resistance?
Air resistance is the frictional force that opposes the motion an objects moving through the air
What's terminal velocity?
The terminal velocity is the fastest an object can travel
What's the equation to calculate the momentum of an object?
Momentum = mass x velocity
What's the equation to calculate the change in momentum using force and time?
Change in momentum = force x time
Therefore force is equal to to the rate of change of momentum
What does the law of conservation of momentum state?
The law of conservation of momentum says that momentum cannot be created or destroyed in a collision
What's the equation to calculate the change in momentum of an object?
Change in momentum = mv - mu
