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.
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
I need the answers for the quick check please!!!
Thank god, this has lasted me three hours this stupid assignment, I hate these poor lessons.
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.
bob can u just answer the question.
100% correct !!!1
!!!1 is correct! THANK YOU
The correct answer to this question 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 problem with the student's experiment design is that the objects used are not comparable in terms of size, shape, and mass. When conducting a gravity experiment, it is important to control all variables except for the one being tested, which in this case is gravity. By using objects that are different in size, shape, and mass, any differences in drop times cannot be solely attributed to the effect of gravity. Other variables like air resistance and object-specific factors may influence the results. To conduct a more reliable experiment, the student should choose objects that have similar characteristics and only vary in terms of the variable being tested (in this case, gravity).
