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.

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

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.

Scalars have magnitude (or size) ONLYYou 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.

Vectors have magnitudeAND 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

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.

Real World Application: FootballA 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

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

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.

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.

Phabulous Physics: Vectors

Displacement Displacement is an object’s change in position.

Distance is the total length of space traveled by an object.

Distance? [How far has the scientist traveled?]

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

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?

Guided Practice

Guided Practice

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?

Exit Ticket

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.
