Physics Quiz

A student slides a book across a desk by giving it an initial push. Which of the following best explains what causes the book to eventually stop?

• Friction occurs when the book rubs against the desk and it stops the book.

• The mass of the book was not enough to keep the book in motion.

• The initial force was too weak to keep the book in motion.

• The magnetic force from the Earth stops the book.

The image above shows two bumper cars colliding. Which of the following explains why the bumper cars are an example of Newton's law of action-reaction?

• The bumper cars move in opposite directions due to equal forces.

• The bumper cars accelerate depending on their mass and the force applied.

• The bumper cars will move in a straight line until acted upon by an unbalanced force.

• All of the above are valid explanations for the motions of the bumper cars and Newton's law of action-reaction.

Which of the following explains why swimming is an example of Newton's law of action-reaction?

• As the swimmer pushes the water forward with their arms, their body moves forward.

• As the swimmer pushes the water backwards with their arms, their body moves backwards.
