Name 1 of Newton's 3 Laws of Motion
1- An object at rest stays at rest, and an object in motion stays in motions unless acted upon by an unbalanced force. 2- As mass increases, acceleration decreases.... as force increases, acceleration increases 3- For every action, there is an equal and opposite reaction
