Elevation vs. Time

Elevation vs. Time

Explanation of Elevation vs. Time Graph

In the video you can see that the guy is walking up the stairs in a constant rate. Looking at the graph, you can see that as time goes on the guy’s elevation is rising. Within 6 seconds his elevation is 21 inches off the ground and his elevation continues to increase by 7 until he reaches the top of the stairs. At the top of the stairs, you can see that the graph comes to its highest peak. He then returns back down to 0 inches, which is back onto the floor (origin) where he first started. The graph shows a clear increase, and then a decrease. Which represents how he walked up the steps (increase) and back down (decrease)
in our explanation of the elevation vs. time graph, we also identified four points and explained what they meant.

The first point we identified was point (4, 14) The x in this ordered pair represents time and the y represents elevation. Therefore the point (4,14) means that at 4 seconds, Dashawn was 14 inches off of the ground.

The second point we identified was point (11, 49) This ordered pair represents that at 11 seconds, Dashawn was 49 inches off of the ground.

The third point we identified was point (24, 35) This ordered pair represents that at 24 seconds, Dashawn was 35 inches off of the ground.

Finally, the fourth point was (27, 14) This ordered pair represents that at 27 seconds, Dashawn was 14 inches off of the ground.

Distance vs. Time

Distance vs. Time

Explanation of Distance vs. Time Graph

In this video you can see that the car is traveling a constant distance over time. You can see that the car’s speed first was a constant rate, and then as times goes one it slows down a little and then speed back up and so on. Nevertheless, as time goes on the farther the car goes from when it first started. in 5 seconds the car only traveled 18 inches, then in 10 seconds it traveled 36 inches, and then farther and farther. Basically, as the wooden car’s distance increased, the time it took to get across the floor increased as well.

In our explanation of the distance vs. time graph, we also identified four points and explained what they meant.

The first point we identified was point (10, 36) The x in this ordered pair represents time and the y represents distance. Therefore the point (10, 36) means that at 10 seconds the wooden car was 36 inches across the floor.

The second point we identified was point (25, 93) this means that at 25 seconds, the wooden car was 93 inches across the floor.

The third point we identified was point (35, 138) this means that at 35 seconds, the wooden car was 138 inches across the floor.

Finally, the fourth point was (20, 79) this means that at 20 seconds, the wooden car was 79 inches across the floor.

Distance vs. Elevation

Elevation vs. Distance

Explanation of Distance vs. Elevation Graph

In this video you can see that the guy was walking at a 0 elevation because he’s still on the floor, but the more he walks the farther the distance he’s traveling. When he steps on the chair and then the table, his elevation rises. The fact that he is still walking does not affect the distance. Once he’s at a distance of 77 inches he has an elevation of 16, and then when his distance is 142 his elevation of 28 inches. Basically, the elevation did not have any effect on the distance so there was no consistent increase of the x nor the y.

In our explanation of the elevation vs. distance, we also identified four points and explained what they meant.

The first point we identified was point (77, 16) The x in this ordered pair represents distance and the y represents elevation. Therefore the point (77, 16) means that when Dashawn was 77 inches across the table, he was 16 inches of the ground.

The second point we identified was point (142, 28) this means that when Dashawn was at a distance of 142 inches, he was 28 inches off the ground.

The third point we identified was point (202, 0) this means that when Dashawn was at a distance of 202 inches he was 0 inches off the ground.

Finally, the fourth point was (0,0) this that when Dashawn was at a distance of 0 inches he was 0 inches off the ground (at rest)

Inverse of Distance vs.Time Graph

Our inverse is a function.

Why our Elevation vs. Time looks different from our Elevation vs. Distance graph

The elevation vs time graph is different from the elevation vs distance because in elevation vs distance time is not being plotted instead we are using elevation so the points or numbers recorded will be higher than time.
