Presentation Transcript

  1. Section 2: Newton’s Laws

  2. Newton’s 1st law: Inertia: Demo: Hammer and Blocks Table Cloth: Balloon and Marbles:

  3. Reflection Questions • The first law of motion states that no forces is required to maintain motion. Then why do you have to keep peddling to maintain motion? • An elephant and a mouse have the same weight of zero in space. It they were both moving at the same speed toward you, which would have the greatest effect? Explain.

  4. Net Force Review: Find the net force (unbalanced force):

  5. Newtons 2nd Law: Describe what you need to consider when designing a racecar: Demo: Students on skate board

  6. Sample Problem 1: Find the acceleration

  7. Sample Problem 2: Find the mass

  8. Sample Problem 3: Find the acceleration of the system

  9. Text Problems Pg 57: (26, 27, & 29) Pg 71-73: (2, 7, 8, 19, 20, 25, 27, 28, 43)
