    2. A brick and a block are pushed with the same amount of force. The brick has 3 times the mass of the block. Which of the following is true about their acceleration?
    a. The block’s acceleration is 3 times faster because it has less mass.
    c. The acceleration is the same.
    d. Neither will move because of inertia.
    b. The brick’s acceleration is 3 times faster because it has more mass.

    4. If the same braking force is applied to a small car & a large truck, which will slow down more quickly?
    a. The small car because it has less mass.
    b. The small car because it has more inertia
    c. The large truck because it has more mass
    d. The large truck because it has more inertia.

    5. Rachel wants to conduct an experiment to test the effect of mass on force. Is the design below a good design? Why?
    Question Image
    c. No, because it tests the effect of acceleration, not mass.
    a. Yes, because it changes mass as the independent variable.
    b. Yes, because it changes height as the independent variable.
    d. No, because it changes more than 1 variable.

    14. According to Newton’s 3rd Law, if the man exerts a force of 100 N on the wall, what will happen?
    Question Image
    b. The wall will exert an equal force of 100 N back on the man.
    d. The wall will collapse because the wall is not exerting a force back on him.
    a. The wall will exert a smaller force back on the man because of the friction.
    c. The wall will exert a stronger force on the man, causing him to fall back.

  • Q15
    15. How does Newton’s Third Law apply to a balloon being thrown across the room?
    a. The balloon will remain in motion until gravity pulls it down.
    b. The balloon will remain in motion until it runs out of air.
    d. If the balloon pushes out the air, then the air will push back on the balloon causing it to move forward.
    c. If more air is put in the balloon, then it will travel further because the greater mass increases the force.
