5. Forces and Motion-I Newton's First Law:
... (a) A constant force is exerted on a cart initially at rests on an air track with negligible friction. The force acts for a short time interval to give the cart a certain final speed. To reach the same final speed with a force that is only half as big, the force must be exerted for a time interval: ...
