- Prebell – Read pg 157 of your textbook and explain, in terms of force and motion and Newton’s Laws, why it is more dangerous to drive on a wet road than a dry one.
- Discuss friction – what causes friction, what would happen if there was no friction, static friction vs. kinetic friction, coefficients of friction
- Friction Problems –
- Guided Practice – work through several problems together as a class
- Independent Practice
- Closure – work through some of the more difficult problems together
- Prebell – Describe a world without friction.
- Friction Lab – students will determine the coefficient of friction for various surfaces
- Closure – write conclusions and answer questions concerning the lab
- Prebell -- Why is static friction greater than kinetic friction?
- Problem solving with force
- Find the net force acting on an object
- Draw force diagrams
- Use equations from previous chapters in combination with Newton’s laws to solve problems.
- Students will review the test they have already taken on Force and Motion to identify weak points and review concepts.
- Review for test
- Problem solving
- Physics Jeopardy
- Closure – ask students test questions from tomorrow’s test
- Prebell – Give an example of Newton’s Laws on action. Justify how your example illustrates Newton’s Laws.
- Closure – Review Balloon Car info and discuss project. Project will be due Monday.
