Two students (A and B) are wearing in-line roller skates as shown in the diagram. If Student A pushes by straightening her arms while Student B keeps her arms in the original position, what would describe the motion of the students?

• Student A does not move, and Student B moves backward.

• Student B does not move, and Student A moves backward.

• Both students move in opposite directions.

• Both students move towards each other.

The images show a person moving forward on a skateboard and a rocket moving upward once launched. What can be concluded about the forces experienced by the two objects?

• The action force cancels out the reaction force.

• The action force is greater than the reaction force.

• The action and reaction forces act on the same object.

• The action force has an equal and opposite reaction force.

A baseball player hits a baseball with a bat during a game. If the force exerted by the ball on the bat is 16,000 N, how would the magnitude force exerted by the bat on the ball compare?

• The bat would exert a force equal to the force of the ball on the bat.

• The bat would exert a force greater than the force of the ball on the bat.

• The bat would exert a force smaller than the force of the ball on the bat.

• The bat would exert a force of zero to balance the force of the ball on the bat.

A force is applied to a book on a table from the left, but the book does not move. What reason best explains why the book does not move?

• The applied force on the book is not large enough to overcome the gravitational force.

• The friction force acts on the book less than the applied force.

• The gravitational force acts equally on the book in the opposite direction of the applied force.

• The friction force acts equally on the book in the opposite direction of the applied force.

A carpenter strikes a nail with a hammer. Which description of the forces on these two objects in this scenario is accurate?

• The force of the hammer on the nail is greater than the force of the nail on the hammer.

• The force of the nail on the hammer is greater than the force of the hammer on the nail.

• The force of the hammer on the nail is equal to the force of the nail on the hammer.

• The hammer exerts a force on the nail, but the nail does not exert any force on the hammer.
