Which of the following is an example of a force that acts at a distance? * a bear walking through the woods
a jet ski skimming across the water
a leaf falling off of a tree to the ground
a tennis ball hit by a tennis player's racket

C), Leaf falling off a tree to the ground.

All the all of them are pretty good examples except for A, C is the answer because the leaf would be high up in the tree. The wind would cause force against the tree knocking the leaf down onto the ground. That acts as distance.

Hope this helps! ✨
