  5. QUESTION What is: TRUE, TRUE, TRUE! A force will make an object move, stop moving, and change its direction of movement.

  6. ANSWER • This is the force that pulls any two objects toward each other.

  7. QUESTION What is: GRAVITY

  8. ANSWER • This is what you do to tell that on object is moving.

  9. QUESTION • What is: compare it to other objects.

  10. ANSWER • TRUE or FALSE: Astronauts weigh less on the moon than on Earth because the moon has less gravity than Earth.

  11. QUESTION • What is: TRUE - the moon has less gravity than Earth.

  12. ANSWER This is the force that slows down moving objects.

  13. QUESTION What is: FRICTION

  14. ANSWER • TRUE OR FALSE: Gravel is the best surface to use when you want to have a rollerskate race.

  15. QUESTION • What is: FALSE, FALSE, FALSE. The best surface to have a rollerskate race on is blacktop.

  16. ANSWER This is the energy an object has because it is in motion.

  17. QUESTION • What is: Kinetic Energy

  18. ANSWER • A child sitting at the top of the slide has this kind of energy.

  19. QUESTION • What is: Potential Energy

  20. ANSWER TRUE or FALSE: A battery-powered car uses chemical energy.

  21. QUESTION • What is: TRUE, TRUE, TRUE!!

  22. ANSWER • This is the type of energy that a person uses when pedaling a bicycle.

  23. QUESTION • What is: Mechanical Energy

  24. ANSWER • These are the forms of energy that are produced when a candle is burned.

  25. QUESTION • What is: heat and light energy.

  26. ANSWER • A student rubs a stick across the teeth of a comb. The mechanical energy is being changed into this form of energy.

  27. QUESTION • What is: sound energy

  28. ANSWER • TRUE OR FALSE: When a battery is used to light a bulb, chemical energy is changed into electrical energy.

  29. QUESTION • What is: TRUE, TRUE, TRUE!!

  30. ANSWER • This is the form of energy that is stored by the batteries inside a flashlight.

  31. QUESTION • What is: Chemical Energy

  32. ANSWER • TRUE or FALSE: Having red paint on a wagon help to best reduce the force needed to move the wagon.

  33. QUESTION • What is: FALSE, having wheels on a wagon will best reduce the amount of force needed to move a wagon, not the color of the wagon.

  34. ANSWER • There are three balls with different weights and are rolled down an incline one at a time. They each strike a wooden block at the bottom of the inclined plane. The ball with the ________ weight will move the block the greatest distance.

  35. QUESTION • What is: greatest. The ball with the greatest weight will move the wooden block the farthest from the inclined plane.

  36. ANSWER • When sandpaper is rubbed over wood, both surfaces become warm. This is a result of

  37. QUESTION What is: FRICTION

  38. ANSWER • TRUE or FALSE: If there were no air friction, a thrown ball will still fall to the ground.

  39. QUESTION What is: TRUE. Even without friction, gravity is still acting on the thrown ball.

  40. ANSWER • TRUE OR FALSE: You are doing work when you watch TV.

  41. QUESTION What is: FALSE, but you are doing work when you carry laundry downstairs.

  42. ANSWER This is why it will take more force to push a sled over a rocky road then over ice.

  43. QUESTION • What is: Because of FRICTION

  44. ANSWER This is why it will take more force to pull two friend in a sled than an empty sled.

  45. QUESTION • What is: because there is an increase in mass in the sled (weight of friends).

  46. ANSWER These are the two forces that act on a thrown ball to make it slow down and make it fall to Earth.

  47. QUESTION • What is: GRAVITY and FRICTION

  48. ANSWER • This is what happens to the potential and kinetic energy of a leaf as it falls from a branch to the ground.

  49. QUESTION • What is: The potential energy decreases and the kinetic energy increases.

  50. ANSWER TRUE or FALSE: Two children are lifting boxes that differ in weight. The child that does more work is the one that lifts the box with the greatest weight.
