1. Do Now  Our school is applying for a Samsung Solve for Tomorrow grant and I want some input from you all. If we win this grant, we could win up to $100,000 for a technology grant for this school – something that could help turn us into a REAL science and engineering establishment!  Give your thoughts for the following question on a separate piece of paper.  How do you think science, technology, engineering and mathematics can help your community improve? Be specific.

6. Unit 2 : Kinematics Describes the movement of objects using words, diagrams, numbers, graphs, and equations.

7. What’s the difference between these two measurements? Measurement 1  To get from MASE to Kroger, you need to travel about 15 seconds down Jefferson and about 30 seconds down Cleveland. Measurement 2  To get from MASE to Kroger, I would travel about ¼ mile west from the parking lot and then at the light, I would travel about ½ mile west again, pass the light at Poplar and there’s Kroger. From MASE, Kroger is a little ½ mile southwest of us.

8. Scalars have magnitude (or size) ONLY  You only know size but no direction of movement  How much something has changed position is called distance  Examples: temperature, mass, energy, speed  Demonstration: moving a brick  The brick moved 5 meters.

9. Vectors have magnitude AND direction  A vector is a numerical value (magnitude, or size) in a specific direction  Vectors are drawn as arrows and the direction of the arrow is the direction of the vector while the length of the arrow is the magnitude

10. Vectors  How would you describe the direction of the block moving in terms of a vector quantity?  The brick moved 5 meters to the right  This measurement which includes direction is called a displacement.

11. Real World Application: Football  A quarterback’s pass is a great example of a vector because it has direction (usually somewhere downfield) and magnitude (how hard the ball is thrown)  Video from NBC

12. Real World Application: Billiards/Pool  Billiard ball velocity vector would tell us the speed its going (magnitude) and in what direction  We saw in the video that vectors can be added together to make a parallelogram  This helps us figure out what would happen to one still ball hit by one that is moving at a specific velocity  Billiards players use vectors to predict where both balls will go upon impact

13. Real World Application: Boats and Planes  Imagine a situation where you're in a boat or a plane, and you need to plot a course. There aren't streets or signs along the way. You will need to plan your navigation on a map. You know where you're starting and where you want to be. The problem is how to get there.

21. Distance VS. Displacement  Distance : how much ground an object has covered. Distance is a scalar quantity.  Displacement : The object's overall change in position. Displacement is a vector quantity.

22. Phabulous Physics: Vectors Displacement  Displacement is an object’s change in position. Distance is the total length of space traveled by an object. 5m 3m 1m  mmmm mmm 9135 Distance 7.636ntDisplaceme 22   6.7m Start Finish = 500 m m 500 Distance 0 Displacement   Copyright © 2010 Intel Corporation.

23. Distance? [How far has the scientist traveled?]

24. Displacement? [What is his overall change in position?]

25. Guided Practice  A physics teacher walks 4 meters East, 2 meters South, 4 meters West, and finally 2 meters North.  What is the distance traveled?  What is the displacement ?

26. Guided Practice

28. Independent Practice 1.What is the displacement of the cross-country team if they begin at the school, run 10 miles and finish back at the school? 2.What is the distance and the displacement of the race car drivers in the Indy 500? 3.A person walks 10 meters, then 15 meters. What's the largest possible displacement ? What's the smallest possible displacement ? What's the distance ?

30.  Exit tickets will be my daily way of seeing whether or not you have understood the objectives we have gone over during class each day.  They will NOT be graded for accuracy but WILL be graded for completion so make sure you always try each and every question.  These exit tickets must be done silently and independently. If you violate this, you will lose your participation points for the day.  You must wait to begin your exit ticket until Ms. Kemal says to begin.
