If a ball is thrown in the air and comes momentarily at rest is it at equilibrium?
I thought yes because it's stationary, but then again.. there is a resultant gravitational force.. ?
Also what is "weightlessness" exactly?
Is it when you're in freefall/only gravity acts? so that would be like an astronaut in a satellite orbiting the earth?
