F max = uR
momentum equation
momentum = mass x velocity
what is the impulse?
the change in momentum
impulse equation
impulse = force x time
what fact does conservation of momentum refer to?
total momentum before impact = total momentum after impact
in general, when is work done on an object?
when a force is applied to it and there is motion
work done equation?
work done = component of force in direction of motion x distance moved in direction of force
what does work done against gravity equal?
