Moving Man - V~locity vs. Time GraphsStudent PagesBackground - Remember graphs are not just an evil thing your teacher makes you create, they are a meansof communication. Graphs are a way of communicating by using pictures and since a picture is worth a thousandwords knowing how to make and interpret graphs will save you a lot of writing. (~Learning Goals = The stadents will:Develop a general kqowledge of "Ve!ocity vs. Time" graphs and"Distance vs. Time":graph~o What graphs of a person standing stil! would look likeo What graphs of a person moving away from an observer ata constant speed would look like.o What graphs ofaperson moving towards an observer at aconstant speed would look like.~ o How differences in speed appear on the graphsProcedure - Do tile following activity using this web sitehttp://www.colorado.edu/physics!pheVsimulations-base.htmlThen click on "The Moving Man"Screen 11. Getting started. After~"The Moving Man" is open leave the position graph and the velocity graphopen but close the acceleration graph. Your screen should look like screen 1.2. Making observations. By either clicking on the man or the slider cause the man to move back andforth and observe what shows up on the graphs. Using the axis provided below make sketches ofDistance vs. Time and Velocity vs. Time graphs for the actions described next to each axis.A man moving from 0to !0 at a slow steadypace.-i0 -I0C~)A man moving from 0to 10 at a fast pace.~5...

velocity

Velocip! Graph PracticeAt what time(s) during this graph is the vehicle standing still?During which time period does the vehicle experience the greatestacceleration?~5When are brakes being applied?Describe, the motion of this vehicle from t=0 to t=40 seconds.
