  1. Chapter 4 Review Mr. Hauser

  2. Rules of the Game • Working in TEAMS, you will be asked to answer questions from the assigned chapters. • You have 30 seconds to write the answer down on the dry erase board. • When the teacher says TIME’S UP, a team leader will stand up and show the teacher their answer.

  3. Rules (Continued) • Each correct answer is worth one point, unless otherwise stated. • Teams can lose points for inappropriate conduct, comments, or cheating. • The team with the most points at the end of the game wins!

  4. Question 1 For every action, there is an equal and opposite reaction is a statement of _______________.

  5. ANSWER Newton’s Third Law

  6. Question2 What are the English units used to measure mass? (Write out the word.)

  7. ANSWER Slug

  8. If an object’s mass is increasing while a constant force is applied to the object, the acceleration Increases Decreases Remains the same Question 3

  9. ANSWER A. Decreases

  10. Question 4 Find the mass of something that weighs 56 N. (with proper units)

  11. ANSWER 5.7 kg

  12. Question 5 An object’s resistance to a change in its state of motion is called _________.

  13. ANSWER Inertia

  14. Question 6 The mass of a pet turtle that weighs 10N is about • 1kg • 100kg • 1000 kg • 10 kg • none of these

  15. ANSWER A. 1kg

  17. ANSWER A. 0 Newtons

  18. Question 8 Which has no change in its state of motion? • An object in equilibrium. • An object at rest. • An object moving at a constant speed. • All of these. • None of these.

  19. ANSWER D. All of These

  20. Question 9 If the acceleration of gravity on Jupiter is 3 times that on Earth. What will the mass of 10 kg of copper be on Jupiter?

  21. ANSWER 10 kg (The mass doesn’t change)

  22. Question 10 What is the only quantity that affects the amount of inertia something has?

  23. ANSWER mass

  24. Question11 Newton’s Second Law states • a=F-M • a=F/m • m=F a • F=m/a

  25. ANSWER B. a = F/m

  26. Question 12 A jet has a mass of 100,000kg. Each engine has a force of 50,000N. What is the jet’s acceleration in meters per second squared? • 1 • 2 • 4 • .25 • None of these

  27. ANSWER 1 m/s^2

  28. Question 13 An object is pulled up with a two forces of 20 N and 35 N. However, gravity pulls down on it with 40 N. Find the net force’s size and direction.
