Force=mass x acceleration

Force=mass x acceleration. F=ma. Suppose there are 2 hockey pucks (of equal mass) lying on the ice rink. Using a hockey stick, you slap one puck. Then you slap the 2 nd puck with twice as much force. What happens to the acceleration of the 2 nd puck? Explain your answer.

  1. Force=mass x acceleration F=ma

  2. Suppose there are 2 hockey pucks (of equal mass) lying on the ice rink. Using a hockey stick, you slap one puck. Then you slap the 2nd puck with twice as much force. What happens to the acceleration of the 2nd puck? Explain your answer.

  3. Suppose you push two boxes with a force of 5N. One box has a mass of 1kg and one box has a mass of 2 kg. Which box will speed up faster? Why?

  4. Shelly pushes a .035kg marble with a force of .07N. What is the marble’s acceleration?

  5. A gust of wind causes a .001kg leaf to accelerate eastward by 30m/s/s. What is the force of the wind?

  6. Christina lifts a 12.5kg box, resulting in a net upward force of 50N. What is the box’s acceleration?

  7. A .15kg hockey puck, starting at rest, is pushed so hard that it accelerates by 50m/s/s. What is the force exerted on the puck?

  8. What force should Lori apply to a 5 kg box to give it an acceleration of 2 m/s/s?

  9. If 10N force accelerates an object 5m/s/s, how massive is the object?

  10. Ravi applies a force of 5N to a wagon with a mass of 10kg. What is the wagon’s acceleration?

  11. Luis is trying to pull a wagon loaded with rocks. What can he do to increase the wagon’s acceleration?
