    Why does a falling object hit harder despite having the same force?

    I posed this question to my teacher: I have a 2 kg object and it sits at rest on the floor. The force is mass * acceleration, so it's about 20 N. Now I drop the ball from, say, 20 feet above the ground. Same mass, same acceleration, so it has the same force, 20 N; but we know the object hits...

    Rigid bodies in special & general relativity

    It's often said there are no rigid bodies in relativity. Is the notion of "angle" primary or derived in relativity? Does "angle" require rigid bodies, at least "locally"? For example, to use light rays to measure the metric, do we need mirrors which are "rigid"?
