Review for Physical Science NC Check-In

A wagon is pushed in a straight line. How would an increase in friction on the wagon wheels affect the wagon?

• It would cause the wagon to move faster.

• It would cause the wagon to change mass.

• It would cause the wagon to change direction.

• It would cause the wagon to slow down.

Which best explains why a bicycle slows down when its brakes are applied?

• The brakes heat the rubber on the bicycle tires.

• The brakes add energy to the bicycle.

• The brakes increase the force of gravity on the bicycle.

Jason fills a glass container completely with water and screws the lid on tightly. He places the container in a freezer. Which will most likely result?

• The container will prevent the water from freezing.

• The water will freeze and take up less space in the container.

• The water in the container will expand when it freezes and cause the container to crack.

• The container will absorb heat from the water, causing it to crack.

A ball is kicked and rolls along a level field until it comes to a stop. What is most responsible for the ball coming to a stop?

• air

• gravity

• mass

• friction

If a car is moving backward along a road, can its speed be measured?

• Yes, it can, because the car does not have friction acting on it.

• Yes, it can, because the car travels a distance in a certain amount of time.

• No, it cannot, because speed can only be measured if the car is moving forward.

• No, it cannot, because the distance traveled backward by a car cannot be measured.
