Responses
Mass is a force that attracts objects toward each other.
Mass is a force that attracts objects toward each other.
The mass in an object is variable.
The mass in an object is variable.
Mass is the measure of the amount of matter in an object.
Mass is the measure of the amount of matter in an object.
Mass is measured in Newtons (N).
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)
Responses
The experiment does not test enough objects.
The experiment does not test enough objects.
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 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.
