3. Chapter 2 Lesson 2 Objective Inertia Warm- Up Look in your book and define inertia….please also write down my definition during notes. http://www.bing.com/videos/sea rch?q=crash+test+dummies&view =detail&&&mid=CFE772E974E2A 84A6D2CCFE772E974E2A84A6D2 C&rvsmid=2D17B05247F5D28BC ACB2D17B05247F5D28BCACB&fs scr=0 http://www.bing.com/videos/sea rch?q=crash+test+dummies&view =detail&&&mid=CFE772E974E2A 84A6D2CCFE772E974E2A84A6D2 C&rvsmid=2D17B05247F5D28BC ACB2D17B05247F5D28BCACB&fs scr=0

4. Inertia An object at rest stays at rest unless a net force acts on it. An object in motion stays in motion unless acted on by an equal and opposite force. An objects ability to resist change in motion.

7. Chapter 2 Lesson 2 Objective Practice Vector addition Warm- Up Review Page 59 Extra Credit for those of you that are ready to go when that late bell rings, paper for notes out and HW also out to be graded

8. Vector addition – class practice 1.A ship is heading due west at a speed of 15 km/h. A current is heading due east at 3 km/h. Calculate the velocity. You need magnitude and direction. 2.A ship is heading due west at a speed of 15 km/h. A current is heading due west at 3 km/h. Calculate the velocity. You need magnitude and direction. 3.A ship is heading due west at a speed of 15 km/h. A current is heading due east at 15 km/h. Calculate the velocity. You need magnitude and direction. 4.A ship is heading due east at a speed of 15 km/h. A current is heading due west at 3 km/h. Calculate the velocity. You need magnitude and direction. 5.A ship is heading due east at a speed of 15 km/h. A current is heading due east at 3 km/h. Calculate the velocity. You need magnitude and direction.

9. Skill Practice Complete page 60 with a partner. You may share one paper between you and a partner. On step 6, the requirement for our class is to complete 3 additional examples.

10. Chapter 2 Lesson 3 Objective F= ma – Newton’s 2 nd Law Circular motion Centripetal vs centrifugal Warm- Up What is the formula for velocity? What is the formula for acceleration?

12. F=ma mini Lecture to be used in lab You throw a 0.5 kg ball with an acceleration of 20 m/s 2. What is the force applied?

13. Lab f=ma 1.Measure the mass of the ball and the ping pong ball in grams. Convert to kg. Record don’t forget units. 2.Use a meter stick to measure the distance you want to roll each ball in meters. Record, don’t forget units. 3.Lay both balls on a flat surface. Push a meter stick against both balls at the same time. A picture of this is found on page 68 in your book. 4.Measure the time it takes each ball to make it to the end of the distance you measured. Record, don’t forget units. 5.Repeat this 3 times to get an accurate and average time. Record, don’t forget units. 6.Now that you have distance and time you must fill in the data table.

14. Chapter 2 Lesson 3 Objective F= ma Circular motion Centripetal vs centrifugal Warm- Up Jeremy Wade is a biologist and fresh water fisherman. He has caught several VERY large fish. One had a weight of 400 lbs ( 180kg). If this fish were to fly out of the water and hit Jeremy what force would the fish apply, assuming it has an acceleration of 1.2 m/s2)

16. Practice

19. Chapter 2 Lesson 4 Objective Newton’s 3 rd law- action reaction Warm- Up Look on page 71 and write down Newton’s 3 rd Law…Record this at the top of your lab paper We will also write down his 1 st and second

20. Lab- you WILL need an objective and data, you WILL need the analysis and conclusion. You will NOT need materials, safety or procedure. You will complete the lab on Page 76-77. You will need all 3 of Newton’s Laws at the top of your paper. You will need to write an objective that corresponds to your activity. You will then need to have your data table Complete steps 1-8. You must create a data table to record your results. You may SKIP steps 9 and 10 Pick back up with step 11 and complete 11-14. Record your results to #11 after you perform the activity….Don’t forget to have is approved!!! # 14 is very important- you must write Newton’s three laws and how the motion of the lid relates to EACH law.

21. Lab- you WILL write a formal lab report. You will complete the lab on Page 76-77. You will need all 3 of Newton’s Laws at the top of your paper. You will need to write an objective that corresponds to your activity. Then the materials, safety and procedure. Complete steps 1-8. You must create a data table to record your results. You may SKIP steps 9 and 10 Pick back up with step 11 and complete 11-14. Record your results to #11 after you perform the activity….Don’t forget to have is approved!!! # 14 is very important- you must write Newton’s three laws and how the motion of the lid relates to EACH law.
