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.

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

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

Answer 1

The main issue with Marcus's experiment design is that he is using two footballs, which are the same shape and mass, thereby not including objects with different masses or shapes. This limits his ability to accurately test the effect of gravity on objects with varying characteristics.

The best response is: It does not include objects with different masses.
