1. Newton's Third Law of Motion states that for every action, there is an equal and opposite .
force
velocity
acceleration
momentum
2. When you push against a wall, the wall pushes back on you with a force that is:
Greater than your push
Less than your push
Equal to your push
Zero
3. When a rocket takes off, the action force is the expulsion of hot gases downward, and the reaction force is the rocket moving .
4. The forces described in Newton's Third Law always act on objects.
5. According to Newton's Third Law, action and reaction forces cancel each other out because they are equal and opposite.
