... Problem 11. A toy car on a ramp is given a quick upward push. As a result of the push, the car travels up the ramp a bit, then rolls back down again. As the car is moving up the ramp, the net force on it is: a. Up the ramp, and increasing in magnitude b. Up the ramp, and decreasing in magnitude c. U ...

... When something is at rest it has a certain quality which is very different from the one it has when it is moving. You would feel safe stepping in front of a locomotive and pushing on its nose – if it were at rest. But you would not want to do this if it was moving. Especially if it was moving fast. ...
