Question

drag the item from the item bank to its corresponding match.
a fireman turns on his hose and is knocked backwards.
it takes less force to move a ping pong ball than a bowling ball.
a soccer ball will not move until a player kicks it.
if air lets out of a balloon quickly, it pushes down and the balloon moves up
f = ma
a ball rolling down hill continues to roll until friction makes it slow to a stop.
3rd law 1st law 2nd law

Explanation:

To solve this, we match each scenario to Newton's Laws:

1. A fireman turns on his hose and is knocked backwards: Newton’s 3rd Law (action - reaction: water pushes forward, hose pushes fireman back).
2. It takes less force to move a ping pong ball than a bowling ball: Newton’s 2nd Law ($F = ma$; smaller mass needs less force for same acceleration).
3. A soccer ball will not move until a player kicks it: Newton’s 1st Law (object at rest stays at rest until a force acts on it).
4. If air lets out of a balloon quickly, it pushes down and the balloon moves up: Newton’s 3rd Law (action - reaction: air pushes down, balloon pushes up).
5. $F = ma$: Newton’s 2nd Law (defines the relationship between force, mass, and acceleration).
6. A ball rolling down hill continues to roll until friction makes it slow to a stop: Newton’s 1st Law (object in motion stays in motion until a force (friction) acts on it).

Answer:

• "A fireman turns on his hose and is knocked backwards" → 3rd Law
• "It takes less force to move a ping pong ball than a bowling ball" → 2nd Law
• "A soccer ball will not move until a player kicks it" → 1st Law
• "If air lets out of a balloon quickly, it pushes down and the balloon moves up" → 3rd Law
• "$F = ma$" → 2nd Law
• "A ball rolling down hill continues to roll until friction makes it slow to a stop" → 1st Law
