1. Motion Part 1 Motion diagrams are also called "strobe" pictures because they are images taken at equal time intervals. Here is an example of a hot air balloon rising at a constant velocity a. Draw a motion diagram of a ball rolling across a table at a constant velocity and discuss with your lab group.b. Now add velocity vectors to each ball position in your motion diagram above. Discuss the length of your velocity vectors with your lab group.o. How draw a position vs. time graph that corresponds lo your motion graph above. Use arbitrary units on your x E: y axes
