Question

1. which of the following is an example of a conservative force? the force of friction slowing the wheels of a skateboard on the road. air resistance against a paper airplane thrown. the force of gravity, which pulls an apple to the ground when it falls from a tree. the force from a parent pulling their childs sled in the snow.

Explanation:

A conservative force is one where the work done depends only on the initial and final positions, not the path taken, and mechanical energy is conserved. Friction, air resistance, and the pulling force on the sled are non-conservative forces as they dissipate energy and depend on the path. Gravity meets the criteria of a conservative force.

Answer:

The force of gravity, which pulls an apple to the ground when it falls from a tree.
