A gust of wind blowing east pushes against a ball. When will the wind do work on the ball?

Question

when the ball moves to the east
when the ball moves to the north
when the ball stays in one place
when the ball moves north or south

Answer 1

The wind does work on the ball when it moves in the direction of the force being applied. In this case, since the wind is blowing east, the wind will do work on the ball when the ball moves to the east.

So the correct answer is: when the ball moves to the east.
