A truck and a small car both experience the same amount of force. Which statement best describes how they will accelerate?

• The truck will accelerate more because it has more mass.
• The car will accelerate more because it has less mass.
• They will accelerate at the same rate.
• The acceleration does not depend on mass.
• None of these are correct answers

What does friction do?

• Pushes objects away
• Causes objects to float
• Resists the motion of objects
• Attracts objects to the ground
• None of these are correct

A box slides across the floor and eventually comes to a stop. A student claims that this proves Newton’s First Law is incorrect because the box does not move forever. How would you respond?

• The student is correct; objects naturally stop.
• The student is incorrect; friction is an unbalanced force acting on the box.
• The student is incorrect; objects stop when gravity takes over.
• The student is correct; Newton’s laws only apply in space.
• None of these are correct answers

• It decreases
• It increases
• It disappears
• None of these are correct

A car is moving at a constant speed on a straight road. The driver suddenly applies the brakes, causing the car to stop. Which of Newton’s laws best explains why the passengers lurch forward?

• Newton’s First Law
• Newton’s Second Law
• Newton’s Third Law
• The Law of Universal Gravitation

If an object is moving at a constant velocity, which statement must be true?

• No forces are acting on it.
• The forces acting on it are balanced.
• An unbalanced force is keeping it moving.
• Only gravity is affecting the object.
