Newtons Laws of Motion - Winston Churchill High School
... 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 between the people and ...

Forces and acceleration Newton`s 2nd Law
... By what factor does the acceleration change when you double the force? Triple the force? Although we accounted for the force of gravity pulling on the hanging mass, there are often other forces in the system which may cause the acceleration to be different from what you expect. Compare by calculatin ...
