Free Fall Lab Example

fFree-Fall Acceleration Laboratory LAB REPORT

This is an EXAMPLE of this assignment and what is expected.- DO NOT COPY the information on this example. The information on here is not the correct answers. You will get no credit for copying.

1. Design an Experiment 5 points
I would use three different objects. My objects would be different shapes, difference sizes and difference masses.
I would measure the time it took them to fall form a balcony to the ground.
I would expect the biggest and the one with most mass to fall to the ground first.
If the results were different then I would need to go back to my textbook and re-read the information about this topic. 2. Developing Hypotheses. 4 points (at least 2 hypotheses)
The Earth, Moon and Mars have different atmospheres and things might fall a little differently.
Hypothesis.
If the atmosphere was thick then the objects would take longer to fall. The objects would have a harder time falling through the packed molecules in the atmosphere

I think the moon has a different gravity from Earth, I think it is more gravity.
Hypothesis.
If the gravity of the moon is more then the object will fall slower in the moon
