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! ✨

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
