Find the average distance the carton was moved when the car was at one book. Record the average on the data table. Repeat this step for two and three books.
Make a graph of the height of the book stack versus the average distance the carton was moved. Refer to chapter 2 for information on making graphs.
Drawing Conclusions:
- What kind of energy did the car have at the top of the board? What kind of energy did the car have at the bottom of the board?
- What evidence do you have that the car had different amount of gravitational potential energy at one book, two books and three books?
- At what height did the car have the most gravitational potential energy?
- How does your graph support your answer to question 5?
- What is the independent variable in the experiment?
- What is the dependent variable in the experiment?
- What are the controls in the experiment?
