... To identify all forces acting on an object, ask yourself the following: 1. What objects are “touching” the given object? These are contact forces. 2. What objects exert a force through “action at a distance” such as a gravitational, electrostatic, or magnetic force? These are action-at-a-distance fo ...

... Imagine two objects, one heavy and one light, falling together and tied together by a thin string. Are the objects falling as one object, hence falling faster (because of their increased mass) than if the objects were untethered? If you were falling alongside and you snipped the string, would the ...
