The data in the table were collected when releasing a basketball from the top of a four-story building. Which correctly describes the basketball’s acceleration?

• The basketball was accelerating, but the velocity increased at different rates for each second the ball was falling.

• The basketball had a constant deceleration, because the velocity increased at the same rate for each second the ball was falling.

• The basketball had a constant acceleration, because the velocity increased at the same rate for each second the ball was falling.

• The basketball had a constant acceleration, because the velocity increased at different rates for each second the ball was falling.

According to Newton’s 2nd law, what is the relationship between force and mass?

• The amount of force needed to accelerate an object increases as the mass decreases.

• The amount of force needed to accelerate an object increases as the acceleration decreases.

• The amount of force needed to accelerate an object increases as the mass increases.

• The amount of force needed to accelerate an object decreases as the acceleration increases.

Two shopping carts, one full of groceries and one empty, were pushed with different amounts of force so that they had the same constant velocity. Which shopping cart will require MORE force to stop and why?

• The empty shopping cart because it is moving faster than the full cart.

• The full shopping cart because it has more mass than the empty cart.

• The empty shopping cart because it has less mass than the full cart.

• The full shopping cart because it is moving slower than the empty cart.

Which of the following statements would be TRUE concerning the amount of force needed to accelerate an object and why?

• The basketball would need more force than the bowling ball, because as the mass decreases, the amount of force needed increases.

• The bowling ball would need less force than the basketball, because as the mass increases, the amount of force needed decreases.

• The rock would need more force than the basketball, because as the mass increases, the amount of force needed increases.

• The basketball would need more force than the rock, because as the mass decreases, the amount of force needed increases.

Newton’s Second Law of Motion describes how an object moves when an unbalanced force acts on it. Which of the following statements BEST describes this law?

• The inertia of an object depends on the mass and force applied.

• The work of an object depends on the mass and the force applied.

• The acceleration of an object depends on the mass and force applied.

• The motion of an object depends on an equal and opposite force applied.

The force of 100 N is applied to the front of a truck. Which of the following would balance the force and cause the truck to remain still?

• applying 100 N in the opposite direction because the forces are of equal magnitude and would balance each other out

• applying 100 N in the same direction because the forces are of equal magnitude and would balance each other out

• applying 50 N in the opposite direction because the forces are of differing magnitude and would balance each other out

• applying 50 N in the same direction because the forces are of differing magnitude and would balance each other out
