1. Physics Unit 1 week 1 Newtons 1 st law

2. Key Terms

3. Lesson Objective  All of the Students will be able to describe Newtons 1 st law of motion by solving an inertia problem on an exit ticket with minimum 2 out of 2 questions correctly.

4. You will be successful if…  Make a checklist of the following items and check yourself off during the lesson.  You can use the metric system to describe an objects motion.  You can explain Newtons first law  You can use Newtons 1 st law to describe why a car in a head on collision stops.

5. Were going to use the metric system Fun fact, 1 meter is around 3.2 feet. Or 39 inches long

6. Introduction  Newtons 1 st Law- An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted on by an unbalanced force.  Umm…What does that mean? (stay tuned)

7. Diving in  What does that mean, I need two volunteers… Come up and push on eachtother with an equal force…  Did anyone move?  Now we need a 3 rd person- come up and push on them in the middle-   This one is the 3 rd person.

8. Fun video or picture describing subject  Newtons 1 st law video

9. Deep  Force - A force is a push or a pull. It is a force that started everything in the Big Bang. BUUUUTTTT. In order to describe that, we need to start somewhere else…

10. Position

11.  Show your work  What was the final x value?  What was the initial x value?

12. Ok- Next up!

13. Check-

14. Fun vid or sample vid Velocity

16. Deep

17. Your turn-  Find the acceleration if a car accelerates from v=0 to v= 10 m/s and does so in 5 seconds.  Given- What were you given?  Find- what are you trying to find?  Solution-  Conclusion- What does acceleration mean to you?

18. mass  Mass is measured in kg (kilograms). Weight is different than mass. Your mass doesn’t change, no matter if you were on the moon, mars, pluto, or earth…. So what changed?

19. Explaining weight on different planets

20. Finally- Force! Like the two people pushing each other, if they are pushing with equal force, what do you think will happen?

21. WWE clip-So obviously most forces ARE NOT balanced

22. Vectors  Force is a vector, it has a direction. Since life rarely has balanced forces, we need a way to measure them. To do this, we use vector addition.  Example-

23. Wipeout video clip and problem

24. Supplementary example A force of 10 newtons going right pushes against a 5 newton force going left. Draw both vectors and perform vector addition. What is the resultant vector? What is the resultant force? Check yourself 1,2,3

25. Advanced A go kartDisplacement (meters) Time (s) Test 142 Test2 Test 3 3636 1.5 3 Students tested a go kart over 3 separate distances to find its speed and got the following table of data. What conclusion can you make based on this data? Is there likely any error? Graph the data using excel. Can you use this data to extrapolate how long it will take the go kart to travel 8 meters? Can you use this chart to determine the go karts average velocity?

26. Lab.  Design an experiment.  As a group. Design an experiment to test one of the equations given today. You will need to follow the scientific method and create a presentation outlining your lab report.  You will also create a video that explains the equation you researched and your test and how it resulted for our word wall (so visitors can understand as well).
