Experiment 1
hypothesis |
The angle (vertical or horizontal) effects the time the projectile takes to land from a set height.
procedure |
1.Have speed stay at 50 m/s and the height stay 50m.
2. Run the experiment with the angle set to zero (horizontal) and record the time it takes to get to 0m from 50m.
3. Do the same thing but with the angle at 90 degrees and record data.
4.graph the data found.

data table
Results |
I set up my table so there are three angles to test,0, 45, and 90. When I ran the simulation, I recorded the time it took to land and made a table. What I found does agree with my hypothesis. When the angle is at 0, the projectile takes the shortest amount of time to land. When the angle is at 45 degrees, which is in the middle of 90 degrees, the time it takes to land is 8.43 seconds. The last one is 90 degrees and it takes the longest to land with 11.13 seconds.
conclusion
Now that I have ran the experiment and collected data, my hypothesis is right. I found that angle effects the time it takes to get to 0m from 50 meters. As the angle gets steeper, the time gets longer. The data table showed this because when the angle was horizontal, it did not take long for the projectile to land. On the hand, the biggest angle (vertical), had the longest time. When the angle of the projectile increases, the amount of time increases.
Experiment 2
Hypothesis |
If there is more speed, then the projectile will go farther in distance.
procedure |
1.set height to 60m and angle to 45 degrees.
2. each time set speed to a different speed.
3. record on table on exel
2. each time set speed to a different speed.
3. record on table on exel
Data Table
results |
For this experiment, I set up a distance vs. speed table. I had the speed go up constant by 15 and ran the simulation for the distance. Every time the speed increases, the distance increases. For example, when the speed is 15m/s, the distance is only 50.33m, but for the speed of 30m/s, the distance is 133.21.
conclusion
My hypothesis is right. The more speed, the farther the projectile goes. I know this because my table shows that the increase in speed also increase the distance it goes.
