  2. When the distance from object to another is changing.

  3. What is Motion?

  4. When you know both the speed and direction of an object’s motion

  5. What is Velocity?

  6. An object used to determine if another object is in motion..

  7. What is a reference point?

  8. A force that one surface exerts on another when they rub against each other.

  9. What is friction?

  10. What scientists call a push or a pull.

  11. What is a force?

  12. Speed is the distance an object covers in this unit of ______

  13. What is time?

  14. speed = distance/time

  15. What is the speed formula

  16. The steepness of a line on a graph comparing distance and time.

  17. what is slope?

  18. Speeding up, slowing down, or changing direction

  19. What is acceleration

  20. The large sections of the earth’s crust that slowly move against each other.

  21. What are plates?

  22. An object that circles the earth due to a balance between it’s inertia and the pull of gravity.

  23. What is a satellite?

  24. This occurs when one surface rolls over another surface

  25. What is rolling friction?

  26. A type of fluid friction that makes parachutes function and leaves drift down slowly in the fall.

  27. What is air resistance?

  28. The force left over when two forces add together or subtract from each other.

  29. What is net force?

  30. Measured in newtons, this is a measurement of the mass of an object in Kg times the acceleration of gravity at 9.8 m/s2.

  31. What is weight?

  32. If one object exerts a force on another object, then the second object exerts a force of equal magnitude on the first object.

  33. What is Newton’s Third Law?

  34. This law is represented by the formula F=ma.

  35. What is Newton’s second Law?

  36. This states that the force of gravity acts on all objects in the universe.

  37. What is the Law of Universal Gravitation?

  38. An object at rest stays at rest, and an object in motion stays in motion unless acted on by an unbalanced force.

  39. What is Newton’s 1st Law?

  40. The law behind the reason why the colliding balls on the track and the Newton’s Cradle kept going.

  41. What is the law of conservation of momentum?

  42. In the penny inertia lab, this was the object whose inertia changed from still to moving.

  43. What is a 3 by 5 card?

  44. Students timed a ball rolling down a six meter track and compared average speeds.

  45. What was the acceleration lab?

  46. We measured both the mass and volume of marbles for this lab.

  47. What was the Marble Density Lab?

  48. This lab measured and compared the oscillations of a swinging weight.

  49. What was the pendulum lab?

  50. This lab was used to calculate the average speed of a marble when the track became steeper.
