During a classroom discussion on motion, the teacher instructs the class to write down something that specifically addresses Isaac Newton’s second law of motion. Which of these responses would best represent the second law?

• For every action there is an equal and opposite reaction.

• Every object continues at rest unless acted on by outside forces.

• Acceleration depends on the force applied and the mass of an object.

• Every object attracts every other object and the force is proportional to their masses.

As a car goes through a turn on a level road, what causes the car to travel in this circular path?

• centrifugal force, which is the friction force between the tires and the road

• centripetal force, which is the friction force between the tires and the road

• centrifugal force, which is the inertia of the car

• centripetal force, which is the weight of the car

The graph shows the velocity versus time for a car moving in the x-direction. Which of the following statements describes the motion of the car?

• The car is slowing down in the −x-direction, comes to a stop, reverses direction, and speeds up in the +x-direction.

• The car is slowing down in the +x-direction, comes to a stop, reverses direction and speeds up in the −x-direction.

• The car is slowing down in the +x-direction, and comes to a stop at t=4.0 seconds.

• The car is speeding up in the +x-direction, and reaches top speed at t=4.0 seconds.
