1. The problem statement, all variables and given/known data Suppose you were kidnapped and held prisoner by space invaders in a completely isolated room, with nothing but a watch and a pair of shoes (with shoelaces of known length). Explain how you might determine whether this room is on earth or on the moon. 2. Relevant equations ang. velocity (W) = square root of (g/L) W= 2 pi (f) 3. The attempt at a solution Ok- I know that gravity is less on the moon than here on earth, so the frequency would be slower. I know that this has something to do with comparing frequency's of the watch and of a pendulum (dangling shoes or watch (?) from shoelaces) but I'm not making the connection on how a person would do this.
