Class this week: This week, we are studying speed - how to calculate and graph it! Ask your child about the "Speed Machines" sheet. We have calculated the speed of some of the fastest vehicles in the world and watched short video clips of them. For perspective, we've been comparing all of these fast speeds to how fast you might drive on Hwy 540 or through a parking lot or neighborhood. On Friday, we will time Hot Wheels cars on a track and see how much human error plays into detecting and calculating speed. We will also graph the speed of our Hot Wheels cars.
Table of Contents: MOTION - These papers should currently be organized in your binder!

What is her speed? Use the speed equation and show your work. 3.Kyle walks 3 blocks south from his home to school. Aliyah walks 2 blocks north from her home to Kyle’s home. How far and in what direction is the school from Aliyah’s home? Draw it out! Thursday, 9/19 HW: None. Test on Motion and Speed most likely on Thursday, 9/26. Will confirm Monday.

What is the zebra doing at points 2 to 3? 2.D 22: Draw vector arrows to represent the speed of two cars moving east on your paper where one car travels further than the other. 3.D 25: What is the relationship between speed and velocity? Friday, 9/20 HW: None. WU: 1.A car traveled 50 miles in 4 hours. What was it’s speed? s = d/t 2.A swimmer swam at a speed of 1.5 m/s for 25 s. What was her distance? d = s x t 3.A runner ran at a speed of 2 m/s for a distance of 440 meters. How much time did it take? t = d / s Comments are closed.
