... • A force is described as the “push” or “pull” between two objects • There are two kinds of forces 1. Contact forces where two objects exert their force upon each other through physical contact, and 2. Action-at-a-distance forces where physical contact is not required to exert a force (e.g., gravity ...

... The California Department of Motor Vehicle Handbook states that if one is driving at a speed of 65 mph and applies the brakes, then it takes a distance of 234.7 feet to come to a stop. What value for acceleration does the DMV use for a car? If we assume that the car slows down with a constant accele ...
