When Thomas pushes a skateboard, it pushes back with an equal force. What does this illustrate?

• For every action, there is an equal and opposite reaction.

• The acceleration of a skateboard is directly proportional to the net force Thomas applies.

• A skateboard at rest stays at rest, and a skateboard in motion stays in motion unless acted upon by an external force.

• The force of gravity acts between all masses in the universe.

What is the formula for calculating force according to Newton's Second Law of Motion?
