Name 1 of Newton's 3 Laws of Motion
1- An object at rest stays at rest, and an object in motion stays in motion 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
