Objects that move differently can end up tracing the same trajectory in space.[br][br]Here are the paths that were traced by two such objects.[br]They each traversed the same parabola in space.[br][br]What becomes clear when you look at where they were at discrete times during their motion is the fact that they moved [i][b]differently[/b][/i] in time. [br][br]For each of the motions, can you sketch the vertical and horizontal position as a function of time?[br][br]For each of the motions, can you sketch the vertical and horizontal velocity as a function of time?[br][br]Can you suggest physical situations that might give rise to these two different motions?[br][br][color=#ff0000][i][b]What other questions could/would you ask your students based on this applet?[/b][/i][/color]
