  1. Newtonian Jeopardy!

  2. Newtonian Jeopardy! Final Jeopardy

  3. What is a Force?

  4. A Force is a push or pull on an object. Back to Menu

  5. What are the 2 types of forces? Explain how they are different and what they result in.

  6. Balanced: equal but opposite forces create a net force of 0; there is no movement. Unbalanced: unequal forces create a net force; object moves Back to Menu

  7. State Newton’s 1st Law of Motion. What is it also known as?

  8. “An object at rest will remain at rest, and an object will remain in motion unless acted upon by an unbalanced force.” Also known as the law of Inertia. Back to Menu

  9. What is Inertia? What propertydoes depend on? (What kind of object would have a high inertia?)

  10. Inertiais an object’s resistance to change in its motion. It depends on the object’s Mass. The greater the mass, the more resistant an object is to change – it requires more force to move. Back to Menu Final Jeopardy

  11. State Newton’s 2nd Law of Motion.

  12. The net force on an object is equal to the product of its massand its acceleration. F = mxa Back to Menu

  13. A 46kg cannonball is shot out of a cannon. If it is accelerating at 5m/s2, what is the Force acting on it?

  14. F = mxa F = 46kg x5m/s2 F = 230 Newtons Back to Menu

  15. How can Newton’s 2nd Law be rewritten to solve for Acceleration? For Mass?

  16. F = m x a a = F m m = F a Back to Menu

  17. You are doing your part to keep the science room clean by flipping your lab stool onto the table. The stool has a mass of 4kg. When flip the stool up, it accelerates at 2m/s2. How much force do you generate by flipping the stool? Unfortunately, NO ONE else is helping. So you stoically flip your stool and 33 others. Force?

  18. F = mxa F=4kg x 2m/s2 = 8N (for one stool) 8N x (33 + 1 stools) = 8 x 34 = 272N Back to Menu Final Jeopardy

  19. What is Kinetic Energy?

  20. Kinetic Energy is the energy of motion. Back to Menu

  21. What is Newton’s 3rd Law of Motion?

  22. Newton’s 3rd states that for every action, there is an equal and opposite reaction. Back to Menu

  23. What are 2 ways that you can increase an object’s Potential Energy?

  24. By increasing the height of the object OR by stretching it. Back to Menu

  25. Which has more Momentum? A 6kg sledgehammer swung at 1.5m/s. A 2.5kg hammer swung at 4m/s.

  26. Which has more Momentum? Momentum= 6kg x 1.5m/s Momentum = 9kg.m/s Momentum= 4kg x 2.5m/s Momentum = 10kg.m/s Back to Menu Final Jeopardy

  27. Define Energy and what is its unit?

  28. Energyis the ability to do Work, measured in Joules. Back to Menu

  29. Energy comes in 6 different forms. Name 3 of them. DAILY DOUBLE!

  30. Mechanical Thermal Chemical Electrical Electromagnetic Nuclear Back to Menu

  31. What is Nuclear Energy, and how can it be released?

  32. Nuclear Energy is the energy stored in the nucleus of an atom, released during fusion (combining) or fission (splitting) of atoms. Back to Menu

  33. What is Thermal, Chemical and Electrical Energy? Give an example of each or how you would measure them.

  34. Thermal: energy of particles in an object; measure with thermometer – Ice Chemical: energy stored in chemical bonds; Fire Electrical: energy of moving electric charges; Lightning Back to Menu Final Jeopardy

  35. What does this diagram represent?

  36. The diagram represents an unbalanced force with the net force in the downward direction Back to Menu

  37. The wagon of girl scout cookies you need to move has just too much inertia. Using Newton’s 2nd Law, how can you move the wagon? 5 Point Bonus:What is a second way?

  38. You can decrease the wagon’s mass by removing some cookies. Or you could reduce the friction on the wheels with ice or oil. Back to Menu

  39. Explain where the Kinetic energy and potential energy are both at their highest and lowest in the diagram.

  40. Kineticenergy is highest at point 3 and lowest at 1 and 5. Potentialenergy is highest at points 1 and 5 and lowest . Back to Menu

  41. While you were floating in space taking pictures with your camera, a small asteroid hit your ship and pushed it away from you. How can you use Newton’s 3rd Law to get back to your ship?

  42. By throwing your camera! Newton’s 3rd Law: Action Reaction is = and opposite The force you exert throwing your camera is equal to the force the camera exerts on you, moving you back towards your ship. Back to Menu Final Jeopardy

  43. 60 30 10 _______ is famous for “discovering” __________ . His observations on objects in __________ revealed that acceleration due to gravity is _____ . His laws of ________ help us understand the behavior of objects. These rules, in order, are ________ , F = m x a, and __________ . It took until the 1900’s before these laws were improved by _________. motion free fall conservation 9.8m/s2 gravity Einstein Momentum Newton inertia 4.9m/s

  44. STOP

  45. Newtonis famous for “discovering” gravity. His observations on objects in free fallrevealed that acceleration due to gravity is 9.8m/s2. His laws of motionhelp us understand the behavior of objects. These rules, in order, are inertia, F = m x a, and momentum. It took until the 1900’s before these laws were improved by Einstein.
