Your friend argues that holding a heavy weight in the air requires a lot of work. According to physics, how much work does it require to hold a 500 N block a distance of 2.0 m above the ground? It requires 500 J of work.

It requires 500 N of work.

It requires 500 x 2 = 1000 J of work.

It doesn't require any work to hold a block above the ground because there the block isn't being pushed through any distance.
