... “My man Newton put it nicely, an object at rest stays at rest, and an object moving stays moving. You are the object, you are at rest. When the elevator pushes you up, your body ‘stays’ there, it doesn’t want to move. Then, the gravitational force pulls you down, resulting in the increase in mass.” ...
