Question

Drag the item from the item bank to its corresponding match.




A. A fireman turns on his hose and is knocked backwards.
B. It takes less force to move a ping pong ball than a bowling ball.
C. A soccer ball will not move until a player kicks it.
D. If air lets out of a balloon quickly, it pushes down and the balloon moves up.
E. F = ma
F. A ball rolling down hill continues to roll until friction makes it slow to a stop.

1. 3rd Law
2. 1st Law
3. 2nd Law

Answer 1

Here are the matches for the items with the corresponding laws of motion:

- **A. A fireman turns on his hose and is knocked backwards.**
**1. 3rd Law** (For every action, there is an equal and opposite reaction.)

- **B. It takes less force to move a ping pong ball than a bowling ball.**
**3. 2nd Law** (F = ma; this explains how acceleration depends on mass and force.)

- **C. A soccer ball will not move until a player kicks it.**
**2. 1st Law** (An object at rest will stay at rest unless acted upon by a net external force.)

- **D. If air lets out of a balloon quickly, it pushes down and the balloon moves up.**
**1. 3rd Law** (For every action, there is an equal and opposite reaction.)

- **E. F = ma**
**3. 2nd Law** (This is the formula stating that force is equal to mass times acceleration.)

- **F. A ball rolling down hill continues to roll until friction makes it slow to a stop.**
**2. 1st Law** (An object in motion stays in motion unless acted on by an external force.)

So the organized matches can be summarized as:

1. A - 3rd Law
2. B - 2nd Law
3. C - 1st Law
4. D - 3rd Law
5. E - 2nd Law
6. F - 1st Law
