Question

drag the missing word into place because work just means that something moved, it takes to make it do what it do. energy friction velocity

Explanation:

In the context of physics (a subfield of Natural Science), work is done when a force moves an object, and energy is required to do work (make something move). Friction is a force that opposes motion, and velocity is a measure of speed with direction, neither of which fit the context of what is needed to make something move to do work. So the correct word is "energy".

Answer:

energy
