Question

which of the following examples best represents newton’s 3rd law?
when riding in a car, your body lurches to the side after an abrupt turn.
a large truck takes longer to slow down than a car.
your stomach jumps when you ride a roller coaster.
pushing water backward with oars helps paddle a canoe forward.

Explanation:

Newton's 3rd Law states that for every action, there is an equal and opposite reaction. Let's analyze each option:

• "When riding in a car, your body lurches to the side after an abrupt turn" represents inertia (Newton's 1st Law), not the 3rd Law.
• "A large truck takes longer to slow down than a car" relates to mass and inertia (Newton's 2nd Law, \( F = ma \)), not the 3rd Law.
• "Your stomach jumps when you ride a roller coaster" is also due to inertia (Newton's 1st Law) as your body resists motion changes.
• "Pushing water backward with oars helps paddle a canoe forward": The action is the oars pushing water backward, and the reaction is the water pushing the canoe (and oars) forward with an equal and opposite force, which matches Newton's 3rd Law.

Answer:

D. Pushing water backward with oars helps paddle a canoe forward
