Acceleration Flashcards
1
Q
air resistance
A
frictional force that opposes motion of objects moving through air
2
Q
speed time graph
A
straight slope shows constant acceleration
3
Q
law of conservation of momentum
A
momentum before collision=momentum after collision
force is equal to rate of change of momentum
4
Q
car safety features
A
seat belts/air bags/crumple zones
increase time for change in momentum, reducing forces involved
