Purpose of Experiment

Does the air pressure in a basketball affect how you play and how your shot outcome? We would like to know because if your gonna do something for a long time in your life, why not do it right from the start?

Hypothesis

The air pressure in a basketball will affect the way you play the game and how your shot outcome percentage is. It also depends on how good your shot is and if you've been playing basketball for a long time.

Travell's Results

Research

Conclusion

At 6 psi, Travell shot 5/10 from the free throw line.

At 7 psi, Travell shot 3/10 from the free throw line.

At 8 psi, Travell shot 7/ 10 from the line.

At 9 psi, Travell shot 6/ 10 from the line.

From our research, we found out that a normal basketball will require 8 Per Square Inch, (psi) for a normal bounce. That showed us that our test would have to be increasing and decreasing the air pressure from the ball. Most of the other websites had information that we already knew about basketballs.

Shooting Results

In conclusion, after all of our research and testing, we decided that our hypothesis wasn't true. The air pressure in a basketball can't affect how you play and how good your shot is. As you can see, the both of us shot 21/40 from the free throw line added up from all the different air pressured balls. Ones shot can defer at anytime and it really doesn't depend on the air pressure in the ball. We can't prove this because we miss shots even when the balls is perfectly inflated.

At 6 psi, John shot 4/10 from the free throw line.

At 7 psi, John shot 2/10 from the line.

At 8 psi, John shot 8/10 from the line.

At 9 psi, John shot 7/ 10 from the line.

Observations/ Results

Materials

  • At 6 psi, ball bounced 35 centimeters.
  • At 7 psi, ball bounced at 38 centimeters.
  • At 8 psi, ball bounced at 41 centimeters.
  • At 9 psi, ball bounced at 45 centimeters.
  • An air pump
  • Four basketballs
  • Two basketball players ( Travell and I.)
  • Basketball Hoop (10 feet tall) and free throw line (15 feet away)

Procedure

  • Step 4, we shot 4 different basketballs that were all at a different psi than the other,
  • Step 5, we recorded our results onto a graph and decided if our hypothesis was correct.

Procedure

  • Step 1, We deflated and inflated basketballs to get them to the right amount of psi that we needed.
  • Step 2, we dropped each basketball from 5 feet high and then recorded our results.
  • Step 3, we walked to the nearest basketball court to do the shooting test.
