  1. Chapter 3 Physics A First Course Forces and Motion

  2. Forces and MotionConservation Laws • 3.1 Newton's Third Law and Momentum • 3.2 Energy and the Conservation of Energy • 3.3 Collisions

  3. Key Question: What makes moving objects keep going at the same speed in the same direction? 3A Investigation: Momentum and the Third Law *Students read text section 3.1 AFTER Investigation 3A

  4. 3A Investigation Topics • Perform collision experiments. • Measure time intervals. • Calculate speed using measured time intervals. • Calculate momentum. • Describe activity using the law of conservation of momentum.

  5. Newton's third law momentum impulse law of conservation of momentum Use Newton's third law to explain various situations. Explain the relationship between Newton's third law and momentum conservation. Solve recoil problems. Chapter 3.1 Objectives and Vocabulary

  6. Key Question: What limits how much a system may change? 3B Investigation: Conservation of Energy *Students read text section 3.2 AFTER Investigation 3B

  7. 3B Investigation Topics • Measure time intervals. • Calculate speed using measured time intervals. • Measure height. • Graph speed vs. height of the car. • Calculate potential energy. • Use energy conservation to derive a formula for the speed of the car in terms of energy.
