Use this outline to take note from the "flipped" video of Ch.1 Lesson 2 "Speed and Velocity."
Acceleration (pg 27) is a measure of how much the velocity of an object changes in a unit of time.
• An object accelerates when its velocity changes as a result of increasing speed, decreasing speed, or a change in direction.
Example: You are riding your bike at a velocity of 5 m/s down your street. A dog starts to chase you so you start to peddle as fast as you can for the next 2 seconds. You now have a velocity of 9 m/s. What is your acceleration? 9 m/s – 5 m/s = 4m/s divided by the time (2s) = 2 m/s/s is your acceleration.

Dr. Shini Somara introduces us to the ideas of motion in a straight line. She talks about displacement, acceleration, time, velocity, and the definition of acceleration. Also, how does a physicist discuss speed as opposed to a police officer? And did you deserve that ticket? You can figure it all out with the help of Physics!

Mr. Causey Shows you step by step how to setup and interpret motion graphs. Learn about both distance versus time and velocity versus time. Also learn the importance of slope for velocity and acceleration.
Mr. Causey will show you how to get the position equations from a motion graph.

Using the data from class create a 4 line comparative graph (1 for each run down the line). Be sure to assign a different color for each run and good luck.
Hint: Don't forget your title, x-axis is the time, and y-axis is the distance (and don't forget your units).
Here are the hosts of Design Squad Nation, Judy Lee and Adam Vollmer, doing the Zip Line challenge. The goal is simple... Design and build something that can carry a Ping-Pong ball from the top of a zip line string to the bottom in four seconds (or less!).

Essential Skill: I can measure the average speed of a moving object and graph the data.
Essential Question: Will things with different shapes and/or sizes have different speeds?
What is speed? And how do we calculate it? Find out in this GCSE / K12 Physics video from The Fuse School.

Can I graph the changing speeds of someone who crawls, walks, or runs?
Using the vocabulary students will write the definition, draw a picture, and think of something that reminds them of the key vocabulary words related to speed.

Mr. Andersen shows you how to interpret a position vs. time graph for an object with constant velocity. The slope of the line is used to find the velocity. A phet simulation is also included.

With many advances in computational methods, researchers increasingly rely more on computers to design airplanes and space vehicles. But, a lot of uncertainty continues to exist in their codes. This research targets finding a way to reduce, if not eliminate, some of the uncertainty.
