Name ____________________________________________ Period ___________ Newton’s Laws & Potential/Kinetic Energy Quiz Review Complete the following table. Term Definition Example from Real Life 1. acceleration 2. centripetal force 3. The pull of a handle on a wagon. 4. inertia 5. mass 6. net force 7. Newton’s first law 8. Newton’s second law 9. When you’re walking, you push backward on the ground, and the ground pushes you forward with equal force. 10. Newton’s second law states that to increase acceleration, you _______________________________________________________________________________ 11. What units are used to measure force? _________________________________________ 12. A wagon is pulled down a hill with a constant velocity. All the forces on the wagon are ___________________________________________________________________ Newton’s Laws and Potential/Kinetic Energy Quiz Review Name ____________________________________________ Period ___________ 13. An action force and its reaction force are ______________________ in size and _____________________ in direction. 14. John pulls a box with a force of 4 N, and Jason pulls the box from the opposite side with a force of 3 N. Ignore friction. In which direction, and with how much force would the box move? 15. List the objects in order from the object with least inertia to the object with the most inertia: Feather, large rock, pencil, book. Explain your reasoning. 16. Explain how an object can have forces acting on it but not be accelerating. 17. What force should Lori apply to a 5 kg. box to give it an acceleration of 2 m/s 2? Use f = m x a 18. If a 10 N force accelerates an object 5 m/s2, how massive is the object? Use f = m x a 19. Ravi applies a force of 5 N to a wagon with a mass of 10 kg. What is the wagon’s acceleration? Use f = m x a Kinetic vs. Potential Energy 20. A skier is on a tall mountain. a. Where does she have the greatest potential energy? b. Where does she have the greatest kinetic energy? Newton’s Laws and Potential/Kinetic Energy Quiz Review Name ____________________________________________ Period ___________ Use the following diagram to answer questions 21 – 22. 21. At which point on the roller coaster will the car have the greatest amount of kinetic energy? 22. At which point on the roller coaster will the car have the greatest amount of potential energy?
