Glossary term: Newton's Laws of Motion

Description: Newton’s Laws of Motion are a set of models which explain how objects with mass change their motion due to interactions with other objects. These interactions are described as forces. Newton's Laws explain how forces affect the motion of objects. Newton developed three laws of motion and a law of gravitation. These laws can explain the motion of most objects in the Universe, with motions involving high velocities and/or very strong gravity requiring Einstein's theories of special and general relativity respectively.
