3. Newton Meets buzz and Woody

4. Order of Notes 1. Contact and Non-Contact Forces 2. CSI Friction Activity 3. Balanced and Unbalanced Forces 4. Newton’s Laws of Motion- Newton Meets Buzz and Woody worksheet. 5. Ch 12 Force and Motion textbook pages

5. Study Guide

6. Jeopardy Procedures/ Rules 1. Work in the group you are assigned. 2. When question is displayed every group must write answer on their whiteboard. 3. The group that holds up their whiteboard first with the correct answer gets chosen. 4. One random person in that group will be called on to explain the answer- so make sure every knows why that is the answer. – If your group gets it right you get the points and get to pick the next question! 5. Most of the questions on this review are questions on your green review sheet- write correct answers as we go over them!

23. $1000 Newton’s Laws of Motion 14. You and your friend smash into each other playing bumper cars and you both move backwards after you hit. This is an example of what law? Explain.

24. Gravity $200 What are 2 factors that effect gravity?

25. $400 Gravity As the force of gravity decrease does the distance from this force increase or decrease?

26. $600 Gravity 11. Why can a satellite move around the earth in a circular orbit at a constant height?

27. $800 Gravity 17. The ball in the diagram is thrown up into the air and follows the path shown. What causes the ball to follow the path beyond point B?

28. $1000 Gravity 6. Why is Earth’s gravity more than the Moon’s gravity?

29. $200 Types of Forces Net Force

30. $400 Types of Forces Friction- Resistance to Motion

31. $600 Types of Forces South Pole of the Magnet! Opposites attract, likes repel!

33. $1000 Types of Forces Contact ForcesNon-Contact Forces 1. Applied Force1. Gravitational Force 2. Normal Force2. Electrical Force 3. Friction3. Magnetic Force

34. $200 Balanced and Unbalanced Forces Newton (N)

35. $400 Balanced and Unbalanced Forces Net Force = 15N Unbalanced Force Object in Motion

36. $600 Balanced and Unbalanced Force Balanced forces have 2 forces that are equal but act in opposite directions and unbalanced forces change in motion, acceleration, and direction.

37. $800 Balanced and Unbalanced Forces Net Force = 55N (30 + 25)

38. $1000 Balanced and Unbalanced Forces The force on the right is greater than the force on the left. The forces are unbalanced.

39. $200 Newton’s Laws of Motion An objects acceleration depends on the mass and the force acting on it. Variables: mass, acceleration, force

40. $400 Newton’s Laws of Motion A = F/m 2m/s 2

41. $600 Identify the type of reaction… For every action there is a reaction for example a rocket launching. Action and Reaction forces are equal but act in opposite directions.

42. $800 Identify the type of reaction… The boat will move backwards or in the opposite direction. Action = reaction.

43. $1000 Identify the type of reaction… Bumper cars are in motion, an outside forces stops the motion (Newton’s 1 st law) The cars move backwards because of Newton’s 3 rd law of motion- action = reaction.

44. $200 Gravity Mass and Distance

45. $400 Gravity Distance increases

46. $600 Gravity Gravity and inertia (keeps it moving)

47. $800 Gravity

48. $1000 Gravity Earth has a greater mass then Mars and Mars has a great mass than the moon. Therefore, earth has more gravity then mars and Mars has more gravity than the moon. Remember Gravity has to do with distance and mass!

49. Good Luck on your test!
