Students analyze their data from a gravity experiment. They find that objects fall at a greater speeed from a greater height than from a lower height what can they conclude

the longer the object falls the greater its mass
the experiment must have a design flaw
students must have mismeasured the objects drop times
the longer an object falls the gravity increases its speed
I think its D but i just wanted to make sure

D. The longer an object falls, the greater the gravity increases its speed.

Thank you I was right
