A block is on a frictionless horizontal table, on earth. This block accelerates at 8.2 m/s2 when a 80 N horizontal force is applied to it. The block and table are then set up on the moon where the acceleration due to gravity is 1.62 m/s2. What is the weight of the
block on the moon?
8.0 N
12 N
10 N
14 N
16 N

If a simple machine reduces the strength of a force, what must be increased?

Explain why electric current cannot exist if a current doesn't have a voltage source.
