Marcus wants to test the effect of gravity on objects with different masses. He drops two footballs from a first-floor window, a second-floor window, and a third-floor window. In each case, he times how long it takes the footballs to reach the ground. What is wrong with his experiment’s design?(1 point)

It does not include objects with different shapes.
It does not include objects with different shapes.

The windows are not high enough to show significant differences in drop times.
The windows are not high enough to show significant differences in drop times.

The drops are not repeated.
The drops are not repeated.

It does not include objects with different masses.

Answer 1

The main issue with Marcus's experiment design is that it does not include objects with different masses. Therefore, the correct response is:

It does not include objects with different masses.

This is crucial because the goal is to test the effect of gravity on objects with varying masses, and dropping only footballs does not provide the necessary variation in mass to evaluate this effect.
