1. Speed Bumps FORCE & ACCELERATION NEWTON’S 2 ND LAW

2. During a collision, how many forces are involved? How do the forces compare in size and direction? ENTRY TASK: Note: Entry Tasks are 10% of your grade

3.  Forces Make a Lovely Pair  Newton’s 3 rd Law Concept Development Practice HOMEWORK QUESTIONS:

4. STATIC FORCES!!! 1000 Kg 1000 Kg What will the Spring Scale read?!

5. CHANGE GEARS!

6. Work TOGETHER With your partner, 1.Match each object with the energy transfer / transformation that would occur 2.Write out the energy change including the starting form and location as well as the ending form and location REVIEW ENERGY

7. 1.Read the WHOLE article (do not answer questions until this is done!) 2.Complete the Think Questions on page 307 3.Complete Remember Questions 1-4 page 312 4.Think Questions 7-14 page 312 ENERGY READING: TRANSFERRING AND TRANSFORMING ENERGY

8. CHANGE GEARS!

9. WHAT FACTORS MIGHT INFLUENCE THE SIZE OF THE FORCES IN A COLLISION?

10. HOW COULD WE MEASURE THE SIZE OF THE COLLISION FORCE? Note: Consider the materials available when answering this question

11. WHAT VARIABLES MIGHT WE NEED TO KEEP THE SAME FOR THE VALIDITY OF OUR EXPERIMENT?

12. 1.Write an investigative Question (this should be similar) 2.Develop a hypothesis (this can be different) 3.Show Ms. Barga ALL at the same time 4.Then explore the materials to develop a procedure. 5.Practice your procedure and create a data table for collecting the information you need (NOT collecting official data YET) 6.When your procedure is clear and consistent and you have a data table, Show Ms. Barga 7.When She Approves, WRITE DOWN YOUR PROCEDURE 8.Use pictures to help you write less words!!! DESIGN YOUR EXPERIMENT

13.  Read Conceptual Physics pages 10-12  Summarize each section in 2-3 sentences  Complete Speed Practice Problems  Complete Static Interactions  Finish Transferring and Transforming Energy Assignment HOMEWORK:
