Background Research:
Momentum- ​the quantity of motion of a moving body, measured as a product of its mass and
velocity.
Angular
​
momentum-​the quantity of rotation of a body, which is the product of its moment of
inertia and its angular velocity.
Mass-​Mass is a measurement of how much matter is in an object. Mass is a
combination of the total number of atoms, the density of the atoms, and the type of
atoms in an object.
​ Center of Gravity- ​the point at which the entire weight of a body may be considered as
concentrated so that if supported at this point the body would remain in equilibrium in
any position
Hypothesis:​ If
Materials:
1 water bottle
Water
Graduated cylinder
Procedures:
1. Fill the water bottle to 20% capacity using the graduated cylinder.
2. Flip the water bottle and record the results.
3. Repeat steps 1 and 2 for a total of 20 flips.
4. Fill the water bottle to 33% of its capacity and conduct 20 flips.
5. Fill the water bottle to 50% of its capacity and conduct 20 flips.
6. Fill the water bottle to 75% of its capacity and conduct 20 flips.

Conclusion: ​The ​conclusion​ is the most important part of your experiment write-up. Be
sure to follow the link so that you can see everything that is required for the conclusion.
Saying you were right or wrong is NOT enough!​ You should:
○ Explain what the purpose of the experiment was
○ Re-state your hypothesis
○ Briefly summarize how you conducted your experiment
○ Explain whether your hypothesis was right or wrong
○ Use your data to support your findings
○ Include any “problems” with your experiment that may have affected the
outcome.
