Check understanding
- States Newton's Third Law correctly, identifying both the action and reaction force and the objects they act on
- Gives at least two real-world examples (e.g. rocket propulsion, swimmer pushing off a wall)
- Distinguishes a Newton's Third Law pair from balanced forces on the same object
- Explains why a gun recoils when fired using Newton's Third Law
“If your child saw a video of a rocket launching into space, could they explain what force is pushing the rocket upward and where that force comes from — and which law of motion that demonstrates?”
