A student designs a gravity experiment. She will time how long it takes different objects to fall from her school’s roof to the ground. She will use three objects: a 2-foot-long board, a toy car, and a paper bag. What is wrong with her experiment’s design?
Gravity will not affect how long it takes for the objects to fall to the ground.
The school roof is not tall enough to test the effect of gravity on different objects.
The objects do not have the same size, shape, or mass, so any differences in drop times cannot be attributed to one variable.
The experiment does not test enough objects.

What about this? The board will fall at different times depending upon if it's dropped "vertically" or "horizontally" because air resistance will affect the "drag". The paper bag will float. What about the temperature that day? What about if the wind is blowing hard.
I need the answers for the quick check please!!!
bob can u just answer the question.
1: Mass is the measure of the amount of matter in an object
2:The objects do not have the same size, shape, or mass, so any differences in drop times cannot be attributed to one variable.
3:Gravity is a force that attracts objects with mass toward each other.
4:By repeating the experiment several times.
5:The longer an object falls, the more gravity increases its speed.

^^^ those are the answers for the Unit 3 Lesson 3 Investigating Gravity Quick Check
Thank god, this has lasted me three hours this stupid assignment, I hate these poor lessons.
100% correct !!!1
!!!1 is correct! THANK YOU
