  3. A1 What happens when two identical forces act on an object in opposite directions? • The object moves in the direction of the first force applied. • The object moves in the direction of the second force applied. • The object accelerates. • The object does not move.

  4. Answer A1 D. The object does not move.

  5. B1 People often use simple machines to assist them in completing tasks. Someone would use a simple machine to: • make work harder • reduce friction • increase work • make work easier

  6. Answer B1 D. make work easier

  7. C1 • Which rollercoaster track should Andrew choose if he wants the roller coaster car to have the most potential energy? C A D B

  8. Answer C1 A

  9. A2 • The tendency of an object to resist changes in motion is called: • inertia • force • acceleration • work

  10. Answer A2 • inertia

  11. B2 • A student slides a book across a desk by giving it an initial push. Which of the following is the MOST important reason that the book eventually comes to a stop instead of continuing to slide? • The initial force was too weak to keep the book in motion. • The mass of the book was not enough to keep the book in motion. • The force that occurs when the book rubs against the desk stops the book. • The magnetic force from the Earth stops the book.

  12. Answer B2 C. The force that occurs when the book rubs against the desk stops the book.

  13. C2 • The type of energy that objects in motion possess is called - • potential energy • kinetic energy • electrical energy • chemical energy

  14. Answer C2 B. Kinetic Energy

  15. A3 What does this instrument measure? • the force of friction on the object • the mass of the object • the force of gravity on the object • the volume of the object

  16. Answer A3 C. the force of gravity on the object

  17. B3 At what point would the Speedy Demon roller coaster car have the most kinetic energy? • 3 • 4 • 5 • 6

  18. Answer B3 C. 5

  19. C3 Compare the acceleration of a large truck to the acceleration of a small car if the same force were applied to each. • car will accelerate less • they will accelerate at same rate • truck will accelerate less • truck will accelerate more

  20. Answer C3 B. The truck will accelerate slower

  21. A4 When Joe jumps to the dock from his small boat, the boat dips into the water. This is an example of – • The Universal Law of Gravitation • Newton's 2nd law • Newton's 1st law • Newton's 3rd law

  22. Answer A4 D. Newton's 3rd law

  23. B4 The unit of force is ____. • m/s • the hertz • the joule • the Newton

  24. Answer B4 D. the Newton

  25. C4 Every force has a(n) ____ force. • reaction • long-range • opposite • accelerating

  26. Answer C4 C. opposite

  27. A5 • You throw a ball into the air. As the ball leaves your hand, the force(s) acting on it is/are ____. • gravity • your hand • balanced • gravity and your hand

  28. Answer A5 D. gravity and your hand

  29. B5 What happens when two identical forces act on a object in opposite directions? • The object moves in the direction of the first force applied • The object moves in the direction of the second force applied. • The object accelerates. • The object does not move.

  30. Answer B5 D. The object does not move

  31. C5 Who invented Battle Ship? • Clifford Von Wickler • Some old guy • That dude off TV • A really bored science teacher

  32. Answer C5 • Clifford Von Wickler

  33. A1 When a car suddenly stops, the objects in the back seat are thrown forward. This is due to: • Newton’s 2nd Law of Motion • The Law of Gravity • Newton’s 3rd Law of Motion • Newton’s 1st Law of Motion

  34. Answer to A1 D. Newton’s 1st Law of Motion

  35. B1 A gunpowder explosion creates hot gases which expand outward allowing a rifle to push forward on a bullet. Consistent with which of Newton’s Laws does the bullet push backwards on the rifle? • 1st Law • 2nd Law • 3rd law • None of the above. The bullet does not push on the rifle.

  36. Answer to B1 B. 3rd Law

  37. C1 What are the classes of levers? • 1, 2, 3 • A, B, C • 1, 2, 3, 4 • Long, Short, and Medium Length

  40. Answer to A2 C. Fulcrum

  41. B2 What simple machines make up an axe? • a lever and a wedge • two levers • a wedge and a pulley • a lever and a screw

  42. Answer to B2 • a lever and a wedge

  43. C2 What decreases friction? • rough surfaces • smooth surfaces • more speed • more surface area

  44. Answer to C2 B. smooth surfaces

  45. A3 What is an example of a simple machine? • baseball bats • scissors • Electric can opener • car

  46. Answer to A3 • baseball bats

  47. B3 What does a mechanical advantage of 4 on a lever tell us? • It is a class four lever. • There are four levers at work. • The lever works four times as hard. • We can lift four times our weight with the lever.

  48. Answer to B3 D. We can lift four times our weight with the lever.
