Question

Drag each example card to the Newton’s law it best represents.
First Law (Inertia) Second Law (F = ma) Third Law (Action-Reaction)
Examples: A filled cart needs a stronger push to speed up than an empty cart. You slide forward in your seat when the car stops suddenly. When you double the force on a skateboard, it accelerates faster. A hockey puck slides far on ice because there is little friction to stop it.

Answer 1

First Law (Inertia)
- You slide forward in your seat when the car stops suddenly.
- A hockey puck slides far on ice because there is little friction to stop it.
(Objects keep their state of motion unless acted on by an unbalanced force.)

Second Law (F = ma)
- A filled cart needs a stronger push to speed up than an empty cart.
- When you double the force on a skateboard, it accelerates faster.
(Acceleration depends on net force and mass.)

Third Law (Action–Reaction)
- None of the given examples directly illustrate the third law.
(The third law is: for every action force there is an equal and opposite reaction force.)
