... changed is the weight. Weight is the mass of a body acted on by acceleration due to gravity. • F = ma where Fw = weight (N) • g = a m = mass (kg) • then Fweight or Fw = mg g = acceleration due to gravity (g) • Example: • A 10.0 kg stone is first held on Earth (g = 9.8 ms-2) and on the moon (g = 1.6 ...

... scale) and downward force (of the weight) must equal a 100 N upward force. Fnet = F scale – W 100 N = F scale - (50 kg)(9.8 m/s2) F scale = 600 N Therefore, the scale will read 600 N Note that this is a heavier reading than if the elevator were at rest. This is often called the “apparent weight”. ...
