Answer to Question #71 in Mechanics | Relativity for Mary

Question

Is it posible to hit some "weightless" material with a "weightless" hammer in a spaceship? Please explain.

Answer 1

When processing the material with a hammer not the weight , but the mass (momentum and energy of the hammer depend on its mass) plays an important role. Body mass in zero gravity is not changed, so it is possible to have the processing.
