Your mass is constant throughout the universe, but your weight changes depending on what planet you happen to be on. For example, because the gravitational force on Mars is less than that on ...

... Two gear wheels, A and B, whose radii are in the ratio RA : RB = 1 : 2, are attached to each other by an endless belt. They are mounted with their axes parallel to each other. The system of two wheels is set into rotation. It is seen that both have the same angular momentum. What is the ratio of the ...
