Free falling and Newtons thought experiment

Make Up:

Loosin my marbles: Set up the experiment as follows. You will need some books to stack. You will need two rulers of some other form of incline. You will need at least 3 marbles, and you will need a paper or plastic cup that is cut in half the long way. See the picture for set up.

The goal of this experiment is to see how height and mass affect the potential energy of an object. Fill in the experimental design box for both the experiments. The IV is stated in the purpose for both and the DV is distance. We are assuming that the distance that the distance the cup moves when hit with the marble is proportional to the total PE at the top of the hill. For the first experiment roll the same marble down the ramp at three different treatments (trt) this would the height of your books. Measure the distance that the cup moved and record in the EDB next to the trial number. Form a conclusion and move to experiment #2.
For #2 change the amount of marbles rolled down at the same time. Measure record and form a conclusion. Graph your data. Remember the IV is on the bottom and the DV is on the side.

Totally Tubular: We did not do this in class, so you may skip it.

Coasting along: Visit the following link, http://science.howstuffworks.com/roller-coaster.htm. This will be a explanation of how roller coasters work. There are seven total pages. Read the text and click next page to continue. On the third page there is an animation of a roller coaster. Play the animation by pressing the button in the top left corner. You will need to draw that diagram in your lab book where it says to sketch the plans of your coaster. Draw their bar graph at each point of the animation by its respective points on your drawing. Write a one page double spaced summary of how roller coasters work and some of the details from the web page. This will cover page 4. Fill in page 5 using the directions and information that you have in your packet. REMEMBER that the total energy is constant through out the entire trip, and that PE is at a max at the top and KE is at a max at the bottom.

Common Cents: Research on the web the difference between mass and weight. Write a summary of your research describing the differences and the similarities at the bottom of page 7. That will be all.

Home work: You will obviously not need to do the book bites on page 11.
For page thirteen you will need to remember that the total energy of a system is always constant and that the KE + PE will always equal the total energy. Look at number 1, both the PE and KE are shown at the bottom, so we add these two and see that the total energy is 50 J, this means that the total energy at any point will be 50 joules. Look athe the top, KE is given, it is zero J, so the PE must be 50 J. In the midle the PE is 25 J, so to add to 50 J the KE has to be 25 J. Complete all the dame way. Also remember that the PE of an object is always the same at the same height. This will be helpful on number 5.
