Friday, 9/18 Unit 1: Linear Motion Pick up a calculator or take yours out…we will not be using our phones as calculators going forward. On your warm-up write the sentence below and fill in the blanks: Draw a velocity time graph for questions 1 and 2 from Wednesday’s acceleration practice questions (note: you do not have to put numbers I am looking for trend lines. Upcoming dates Monday, 9/21 – last day to re-test on unit 1 Tuesday, 9/22 – Quiz Wednesday, 9/30 – Quiz Friday, 10/2 – Unit 2 test Friday, 10/9 – last day to turn in 1NW extra credit Visit my webpage for more important dates

Calculating Acceleration - Example Big Papi, from the Boston Red Sox, is stationary at the plate before hitting the ball. He runs 27.43 meters and reaches first base at a velocity of 2.30 m/s. It takes Papi 12 s to reach first base. Calculate Papi’s acceleration. G:E:S: U:S:

Take out the questions from Monday With your elbow partner do the following: Write the G for each question Write the U for each question Pick an equation to use Determine if you need additional information to solve the question. If so what do you need?

10
Times for your calculations Question NumberTime 17.0 s 2120.0 s 33.0 s 44.0 s

11
Check your answers Question NumberAcceleration 16.42 m/s 2 20.0 m/s 2 30.67 m/s 2 40.0 m/s 2

12
Create a velocity-time graph for each question

13
Cool Down A line on a position time graph represents velocity or acceleration (choose one). Support your answer. A line on a velocity-time graph represents velocity or acceleration (choose one). Support your answer.
