Force/Motion review quiz

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

• The brakes cause frictional forces on the wheels of the bicycle

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

A bowling ball moves across a flat surface at 7 feet per second. If a student is asked to calculate the total distance traveled by the ball, what other information does the student need to know?

• Amount of friction between the ball & the surface

• Amount of force applied to the ball

• Total time the ball rolled

• Mass of the ball
