Answer to Question #235789 in Physics for Saby

Question #235789

This animation will allow you to find the density of a penny, a nickel, and a quarter.

Make a hypothesis in which you suggest which coin will have the highest density and which will have the lowest density. A model hypothesis might be: "If the (fill in the name of a coin) has a greater density than the _____ and _____, then it will have a greater mass to volume ratio. If the (fill in the name of a coin) has a lower density than the _____ and _____, then it will have a lower mass to volume ratio.


  1. According to your data, was your hypothesis correct? (Be sure to refer to your data when answering this question.)
  2. Summarize any difficulties or problems you had in performing the experiment that might have affected the results. Describe how you might change the procedure to avoid these problems.
  3. List at least two real world examples that apply the findings of this experiment. (Hint: An example of this type was given in the introduction to this project.)

"If the nickel has a greater density than the penny and quarter, then it will have a greater mass to volume ratio. If the penny has a lower density than the nickel and quarter, then it will have a lower mass to volume ratio."


  1. Yes, my hypothesis was correct: nickel was of the highest density
  2. The measurements were the most difficult part, as well as the precision of measurements for such small objects.
  3. Estimation of the density of water in the lake/sea by the fact whether I float there or need to swim in order to stay above water surface.
