Review for Forces - The Russell Elementary Science Experience
... Review for Forces I. Vocabulary 1. A force is any push or pull that causes an object to move, stops moving, or changes direction only when a force acts on it. 2. Friction is a force that opposes, or acts against, motion when two surfaces rub against each other. 3. Magnetism is the force of repulsion ...
