Newton`s Third Law
... First, we know that mass m is falling and dragging mass M off the table. The force of kinetic friction opposes the motion of mass M. However, we know that friction is negligible here because it is a smooth surface! We also know, since both masses are connected by a nonstretching rope, that the two m ...

CHAPTER 4 The Laws of Motion
... Newton’s First Law: An object at rest remains at rest and an object in motion continues in motion with constant velocity (constant speed in straight line) unless acted on by a net external force. “in motion” or “at rest” – with respect to the chosen frame of reference “net force” – vector sum of all ...
