Question

1. a car accelerates down the road. what is the

eaction\ to the tires pushing on the road?

the air in the tires moves the car
the mass of the car pushes on the tires
the road pushes on the tires
the road moves away from the tires

Explanation:

To solve this, we use Newton's Third Law of Motion, which states that for every action, there is an equal and opposite reaction. The action here is the tires pushing on the road. The reaction should be a force of equal magnitude in the opposite direction, so the road pushes on the tires. Let's analyze the options:

• Option 1: The air in the tires moving the car is not related to the tires - road interaction.
• Option 2: The mass of the car pushing on the tires is about internal forces or weight - related, not the reaction to tires pushing the road.
• Option 3: According to Newton's Third Law, if the tires push the road (action), the road pushes the tires (reaction) with equal force and opposite direction. This fits.
• Option 4: The road moving away from the tires is not a force interaction as per Newton's Third Law; it's about the force pair between tires and road.

Answer:

B. the road pushes on the tires
