... Example 4: Elevator problems. A body of mass m rests upon a scale in an elevator. The scale will supply the normal force N, keeping the body from falling out of the elevator. The scale will record the force N which is also called the apparent weight of the body. Draw the force diagrams showing force ...

... We can tell if a "force" is fictitious or not by asking whether or not it makes sense when discussed within the context of the 3rd Law. According to the 3rd law, every force is actually a two-way interaction. In the example above, if a force does truly push on the cup, then the cup must also push b ...
