Question

mon 2/9 - show what you know - newtons laws
which is an example of newtons 3rd law.
□ you sitting on a chair, pushing down on the chair and the chair pushes up on you.
□ kicking a ball that was at rest causing it to fly up in the air
□ the seatbelt keeping you from going through a windshield if a car stops suddenly with great force
□ applying greater force to an object that is massive causing it to accelerate

Explanation:

Newton's 3rd Law states that for every action, there is an equal and opposite reaction, meaning paired forces act on two different objects.

• The first option describes your downward push (action) on the chair and the chair's upward push (reaction) on you, which matches this law.
• Kicking a ball relates to Newton's 2nd Law (force causing acceleration).
• A seatbelt stopping you relates to Newton's 1st Law (inertia).
• Applying force to accelerate a massive object relates to Newton's 2nd Law ($F=ma$).

Answer:

A. You sitting on a chair, pushing down on the chair and the chair pushes up on you.
