The goal of this lab is to draw conclusions about motion graphs and practice graphing motion. mtroduction: Motion graphs are important to understand how objects are moving. In this lab activity, we will create motion graphs from motion diagrams and from description situations. O8 ) = 1 s こ=} as 9 =1 8.

The diagram below shows Harold running from 0m to 100m on the track. He is moving along the positions, shown on the number line and his time at each position is tracked above him. Using these values, first create a data table. Then graph the motion (using time on the x and position on the y). Lor on Ceu 0 10 20 30 40 50 60 70 80 90 100 0 10 S0
