Gravity and Motion Answers

The force that contributed to the formation of planets, determines the motion of bodies in the solar system, and pulls objects to the center of Earth is called . Newton’s first law of motion states that an object at rest will stay at rest unless a force acts on it. It also states that an object in motion will stay in motion unless a force acts on the object. Newton’s first law of motion is also known as the law of .
