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?(1 point)
Gravity will not affect how long it takes for the objects to fall to the ground.
The experiment does not test enough 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 school roof is not tall enough to test the effect of gravity on different objects.
Well, her experiment design has a bit of an issue. The objects she has chosen do not have the same size, shape, or mass. So, any differences in drop times cannot be attributed to one variable. It's like trying to compare apples, oranges, and clowns to see which one can do a better dance. They're just not comparable, you know? Maybe she should reconsider her objects and make sure they're on the same page. Or roof, in this case.
The correct answer is: The objects do not have the same size, shape, or mass, so any differences in drop times cannot be attributed to one variable.
The correct answer is: The objects do not have the same size, shape, or mass, so any differences in drop times cannot be attributed to one variable.
The student's experiment is flawed because the objects used in the experiment are not similar in size, shape, or mass. This means that any differences in the time it takes for them to fall to the ground cannot be solely attributed to the effect of gravity. In order to properly test the effect of gravity, it is important to isolate the variable being tested, which in this case is the objects' different properties. Therefore, the student should use objects that are similar in size, shape, and mass for a more accurate experiment.
