The Purpose: The aim of this lab is to find out how the height from which a ball is dropped affects how high it bounces back up. We're gonna look at different types of balls and see the height when dropped. In some videos it shows that it depends on the material if the drop is bouncy or not.

Question

My Hypothesis
I'm hypothesizing that as the drop height increases, the bounce height will decrease(Common sense). I think higher drops will lead to higher bounces based on the energy I've observed in some Video studies.

My Materials
- Different types of balls ig (e.g., tennis ball, basketball, golf ball)
- Measuring tape or ruler
- Stopwatch (if needed for timing bounces)
- Notebook for recording data
- A flat surface to drop the balls

Steps (Procedure?)
1. Get all my materials and find a flat area where I can drop the balls without a bad response.
2. Using a measuring tape to see the drop height, by starting with 20 cm
3. Holding the ball at the measured height and letting it go.
4. Writing the ball point, like where it lands
5. Repeat: the same for 40 cm, 60 cm, 80 cm, and 100 for the drop heights. (e.g., tennis ball and basketball).
6. to drop the balls from the same position every time and drop them vertically.

Data Table !!

| Drop Height (cm) | Bounce Height (cm) (Tennis Ball) | Bounce Height (cm) (Basketball) |
----------------------
| 20 | 12 | 15 |
| 40 | 25 | 32 |
| 60 | 32 | 45 |
| 80 | 45 | 58 |
| 100 | 55 | 70 |

The Graph

(Create a scatter plot with "Drop Height (cm)" on the x-axis and "Bounce Height (cm)" on the y-axis. Title it “Bounce Height vs. Drop Height.” Make sure to create points for each measurement and connect them to visualize the relationship.)

My Observations

During the experiment, I noticed that when I dropped the balls from 100 cm, they usually bounced much higher than those dropped from 20 cm. The basketball bounced higher than the tennis ball because it is made of a material that stores more energy during the bounce. Sometimes the bounce height wasn’t what I expected, especially if the floor was a little uneven. This agrees with real-life studies where the type of ball and surface interacted significantly affected bounce height.

Average Bounce Height for each drop height:
- 20 cm: (12+15)/2 = 13.5 cm
- 40 cm: (25+32)/2 = 28.5 cm
- 60 cm: (32+45)/2 = 38.5 cm
- 80 cm: (45+58)/2 = 51.5 cm
- 100 cm: (55+70)/2 = 62.5 cm

The Conclusion | My Hypothesis & Findings
My hypothesis that higher drop heights would lead to higher bounce heights was mostly supported by the results. The higher I dropped the balls, the higher they bounced in general. The basketball, in particular, had a more consistent bounce compared to the tennis ball.

The Implications of Findings
This suggests that the energy from dropping the ball transfers into how high it bounces back up. The experiments I conducted align with previous real-life studies that show how different ball materials and surfaces affect bouncing dynamics.

Suggestions for Future Research
If I were to do this experiment again, I would try dropping heavier balls to see if they bounce higher or lower than lighter ones. I would also want to test different surfaces, like grass or carpet, to see how they affect the bounce height. It would be interesting to explore how temperature affects the material of the balls and, consequently, their bounce height.

Answer 1

Here is a representation of the graph you would create based on your data:

Bounce Height vs. Drop Height

Y-Axis: Bounce Height (cm)

|                               • (100 cm, 70 cm)

|                • (40 cm, 32 cm)

Make sure to plot the points for both the tennis ball and basketball, each with different markers or colors for clarity, and connect the points for each ball type to visualize the relationship!
