Question

Drag each example card to the Newton’s law it best represents.
First Law Second Law Third Law
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. (Your body wants to keep moving forward when the car decelerates.)
- A hockey puck slides far on ice because there is little friction to stop it. (An object in motion stays in motion unless acted on by a net force.)

Second Law (F = ma)
- A filled cart needs a stronger push to speed up than an empty cart. (Greater mass requires more force for the same acceleration.)
- When you double the force on a skateboard, it accelerates faster. (Acceleration is proportional to the net force.)

Third Law
- None of the given examples directly illustrate the third law (action–reaction pairs).
