AP Physics 1 Table 1: Kinetic and Gravitational Potential Energy of a Simple Pendulum (1 point) Time (s) Kinetic Energy (cm) Gravitational Potential Location of Pendulum Bob Energy (em) Farthest Right: + Bottom/ Center Farthest Left: - Data point 1: Data point 2 Data point 3: Data point 4: Graphs (2 points) Make two (2) line graphs using Excel, Google Sheets, Desmos, Physics Aviary, NCES or whatever virtual platform works best for you. The first line graph should be kinetic energy vs. time, and the second line graph on the same axes, should be gravitational potential energy vs. time. Be sure to label the axes, provide a title, and have different colors for the 2 graphs. Provide a key for which color is which energy. Analysis (10 points) 1. For the original/ initial experiment, at what point is (3 points total): a. the PE the greatest? b. the KE the greatest? c. v (velocity) the highest and the lowest? 2. For the original/ initial experiment, what is the relationship between KE and v? (1 point) 3. Look at your graph. If you were to add a third line, representing the sum of KE and PE at any given point, what would it look like? (1 point) 4. When you changed the length of the string, how did this affect the kinetic energy and gravitational potential energy?

(1 point) When you changed the acceleration due to gravity, how did this affect the kinetic energy and gravitational potential energy? (1 point) 7. What happens to the motion of the pendulum as the total energy increases? (1 point) Part 2 - Pendulum Variables as Related to the Period (21 points) each part, you will need to calculate the period. You will need to use average values for time andPart 1 - Energy in a Pendulum (13 points) Pendulum Lab Directions 1. Go to the PHET Pendulum lab and select "Lab". Y 2. On the right, leave Length, Mass, Gravity and Friction as set. 3. At the bottom left, turn on the ruler and the timer. Lab 4. At the top left, turn on the Energy Graph. 5. At the lower center, turn the speed to "Slow". 6. At the left, drag the ruler to the KE/PE bar graph. 7. Move the bob to an angle of your choice; this will be recorded in the table as + and - for the farthest right and farthest left, respectively. 8. Drag the stopwatch directly near the play button; this will enable pressing the play button and starting the timer as close as 00:01.2s possible. O Norms 9. Press the play button and immediately start the timer. 10. As the pendulum swings, collect data on time and the height of both KE and PE bars at various locations and record in Table 1. 11. The PE and KE can be "measured" based on the ruler in cm (centimeters) as a substitute for energy in J (Joules). 12. For the data points except the "Bottom/ Center," fill in the angle. 13. Use the pause button as needed to record the necessary data. 14. Repeat the same experiment but change the length of the string from 0.70m to another length. Record your observations, as you will need this information to answer a later question. 15. Repeat the same initial experiment but change the mass of the bob from 1.00 kg to another mass. Record your observations, as you will need this information to answer a later question. 16. Repeat the same initial experiment but change the acceleration due to gravity from Earth to another value. Record your observations, as you will need this information to answer a later question. 17. Repeat the same initial experiment but change the friction from 0 to another value. Record your observations, as you will need this information to answer a later question.
