For our graph we decided to see how high Jacksons feet go compared to Dom’s head when he back flips. To do this we went to Gates park to have a flat place for us to do this. First Jackson started out of the frame of the camera then walked into frame as he got closer to Dom, then he did a backflip next to Dom, after he did the back flip he walked in a straight line out of frame.

Title: How high can Jackson backflip
-
X-axis Time (seconds)
-
Y-axis: Feet Height (ft)
-
Key Points: Start (0s), Midpoint Peak (~3.11s), End (6.28s), plus two intermediate points
-
Discrete or Continuous?
Continuous, the height changes smoothly over time. -
Is it a Function?
Yes, each time has only one height. -
Linear or Non-Linear?
Non-linear – the rate of change varies. -
Rate of Change (Example: 0s to 1.6s)
About 1.78 ft/sec = (2.84−0)/(1.6−0). -
Constant Rate?
No, the speed increases then decreases due to jumping motion.
