What is Newton's 1st Law of Motion?

• A body in motion stays in motion, a body at rest stays at rest, unless acted upon by a force.

• Force equals mass times acceleration.

  F =M*A

• For every action there is an equal but opposite reaction.

What is Newton's 2nd Law of Motion?

• A body in motion stays in motion, a body at rest stays at rest, unless acted upon by a force.

• Force equals mass times acceleration.

  F =M*A

• For every action there is an equal but opposite reaction.

What is Newton's 3rd Law of Motion?

• A body in motion stays in motion, a body at rest stays at rest, unless acted upon by a force.

• Force equals mass times acceleration.

  F =M*A

• For every action there is an equal but opposite reaction.
