The Second Law
... Calculating force Three people are each applying 250 newtons of force to try to move a heavy cart. The people are standing on a rug. Someone nearby notices that the rug is slipping. How much force must be applied to the rug to keep it from slipping? Sketch the action and reaction forces acting betw ...

Notes for Unit 4
... *** An object MUST have an unbalanced force acting on it in order to start its motion or stop its motion. The 1st law is also called the Law of Inertia Interia: The tendency for an object to resist a change in motion. Inertia is directly related to Mass. Bigger Mass = More Inertia This is an easy co ...
