5. Jane is riding her bike, she starts to apply more force by pedaling faster what do you predict will change?

• a. Her velocity will increase
• b. Her speed will increase
• c. Her position will not change
• d. Her acceleration will decrease

6. Jess walks at a steady velocity. Her acceleration is

7. A ball is thrown into the air and is put in motion, which is true of the force that put the ball into motion?

• a. The force that put the ball into motion was a balanced force.
• b. The force that put the ball into motion was friction because friction causes motion.
• c. The force that put the ball into motion was an unbalanced force.
• d. The force that put the ball into motion was gravity because gravity causes the ball to fall.

8. A golf ball is sitting on the tee (that little thing that holds golf balls up off the ground so they can be hit), then the golfer swings the club and hits the ball putting it into motion. The ball soars through the air and then hits the ground and rolls to a stop. Which of the following is not true?

• a. The ball was not in motion and therefore would not have moved until the unbalance force of the club was acted upon it.
• b. The ball was being acted on by the force of gravity, and the force of gravity was being balance by the tee, keeping the ball from moving down toward the ground.
• c. The ball was not being acted on by gravity, because the ball was not moving.
• d. The force of friction was acted on the ball when it flew through the air, because there was friction between the air and the ball, and this friction along with gravity would be some of the unbalanced force that brought the ball to a stop eventually after it was hit.

9. Inertia is a ____________ of matter that is based on ______________.

• a. Force, mass
• b. Property, mass
• c. property, weight
• d. force, weight

10. The car turned South on I-95, which of the following describes the car’s movement?
