Why is it important for basketball players to wear shoes with tread when playing?

• To increase the speed of the player.

• To decrease the force between the player and the floor.

• To increase friction between the floor and the player's feet.

• To decrease the amount of force needed for the player to move.

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.

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.
