  1. Newtonian Jeopardy!

  2. Newtonian Jeopardy!

  3. Describe a Force.

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

  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

  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 Inertia.

  9. What propertydoes Inertiadepend on? Explain why.

  10. Inertiadepends on an 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 acceleration and its mass. F = m x a

  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 = m x a F = 46kg x 5m/s2 F = 230 Newtons

  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

  17. A pitcher throws a 0.5 kg softball. When the batter hits it, the force on the ball triples. What happens to the acceleration? If the force on the ball after it is hit is 30N, what is its acceleration?

  18. If the Force is tripled and the mass is unchanged, than the acceleration is tripled. a = F m a = 30N 0.5kg a = 60m/s2 Back to Menu Final Jeopardy

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

  20. Newton’s 3rd states that for every action, there is an equal and opposite reaction.

  21. What is the formula for Momentum?

  22. Momentum = Mass x Velocity

  23. What does the Law of Conservation of Momentum State?

  24. The total Momentum of objects that interact does not change unless acted on by an outside force.

  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 Power? 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. What is Friction?

  28. Frictionis the force that one surface exerts on another. Frictionopposes motion.

  29. What 2 factors does friction depend on? DAILY DOUBLE!

  30. Friction depends on the types of surfaces involved and how hard they press on one another.

  31. Why does an oak leaf take longer to fall to the ground than an acorn?

  32. An oak leaf has a greater surface area, which means it encounters more air resistance

  33. What is Free Fall? What is the acceleration of an object in free fall? What is it called when your free falling velocity has reached its maximum speed?

  34. Free Fall is when the only force acting on an object is gravity. The acceleration of an object in free fall is 9.8m/s2. Maximum speed in this situation is called Terminal Velocity. 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

  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 lubricant.

  39. 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?

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

  41. What does the gravity between two objects depend on? How can you increase / decrease gravity?

  42. The gravity between 2 objects depends on the Mass of the objects and their distance from one another. You can increase gravity by increasing mass / decreasing distance. You can decrease gravity by decreasing mass / increasing distance. Back to Menu Final Jeopardy

  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.
