Question

Anthony is experimenting with how the amount of air inside a basketball
affects how high it bounces. He uses logical reasoning to conclude that he
should drop each ball from the same height. Why is this important?
A. Dropping the balls from different heights would take longer.
B. Dropping the balls from different heights would introduce error.
C. Dropping the balls from the same height will create more data for
the experiment.
D. Dropping the balls from the same height is less fun.

Answer 1

It is important to drop the balls from the same height because : ( B ) Dropping the balls from different heights would introduce error

The experiment Anthony is trying to perform is to determine the effect of the air inside a basketball on how high the ball will bounce, therefore other variables such as height should be kept constant ( i.e the same for every ball to be used for the experiment ).

If anthony drops the balls at different heights that will have a direct effect on the measurement of the bounce heights attained by each ball therefore creating room for error in the experiment .

Therefore we can conclude that It is important to drop the balls from the same height because  Dropping the balls from different heights would introduce error
