1 COURSE UNIT PERIOD PAGE SPH3U Energy Conservation of Mechanical Energy 1 of 2 Overall Expectation D2. investigate energy transformations and the law of conservation of energy, and solve related problems Specific Expectation D2.3 use the law of conservation of energy to solve problems in simple situations involving work, gravitational potential energy, kinetic energy, and thermal energy and its transfer (heat) [AI] Key Performance Task By the end of this lesson, students will have built an understanding (through the use of a simulated pendulum) of the relationship between pendulum height, velocity and energy at varying stages of a pendulum s swing. Prior Knowledge Prior to this lesson, students were introduced to the concepts of gravitational potential energy and kinetic energy and were able to work out basic problems for each independently. Total Mechanical energy was introduced, but the notion of conservation of total mechanical energy is new for this lesson. Activity Description Time Intro Students collect handouts as they enter Attendance is taken as students are seating themselves Ask students to log in to computers as they come in the room so that there is no delay in getting started (machines can take a while) 5 min Review and Prior Knowledge Brief review of gravitational potential energy and kinetic energy Take up questions from previous days homework if any When review is done, introduce today s task of better understanding the velocity, height and energy in a swinging pendulum The prior knowledge questions from the Explorelearning.com worksheet to be completed immediately As students are working on these questions, assign groups for later part of the lesson (see special accommodations) 20 min Explorelearning Gizmo Student groups are to use the computer at their lab station to go to and enter the class code:fwprzxsg33 Once logged in, students are to click on Energy of a Pendulum gizmo From this point forward, students can follow the handout and work through each of the three parts (15 minutes each): Part A: Potential and Kinetic Energy Part B: Calculating Potential Energy Part C: Kinetic Energy and Velocity 45 min
2 An audible alert should be given to students when it is time to move on from part A to B and B to C. In the last minute of part C, students are to log off and return to their seats with their worksheets Summary A brief summary of the key ideas including the balance between kinetic and potential energy and the idea that the total mechanical energy is the constant if heat loss is negligible. Students should be made aware that the worksheets will be collected at the beginning of next period for marking. 5 min Modifications For students who may not be computer savvy, groups will be selected so that there is a mix of ability, gender, etc. The teacher will migrate from group to group asking key questions to ensure understanding. Students who need extra time on the computer can be accommodated at lunch and can also access the explorelearning.com site from home to see the virtual experiment again. Required Equipment and Materials Computers with internet access (minimum one computer per group of 4) Explorelearning.com student worksheet (Energy of a Pendulum) Extensions Students who complete the exercise early can use logger pro along with motion sensors to set up a real pendulum and compare it with the ideal case presented in explorelearning.com The real case introduces the dampening of the sinusoidal function of the amplitude versus time as in the real world there is air resistance slowing the pendulum. Notes Using a simulation for this lab is beneficial as it allows all the students to progress at their own pace (if a full computer lab is in use) The simulation also allows for easy modification of the factors within the experiment Extra time is easily provided for those students who do not finish as they can access the virtual lab from home very easily.
3 Name: Date: Student Exploration: Energy of a Pendulum Vocabulary: conservation of energy, gravitational potential energy, kinetic energy, pendulum, potential energy, velocity Prior Knowledge Questions (Do these BEFORE using the Gizmo.) 1. A toy car is about to roll down a track, as shown below. At what point do you think the car will reach its greatest speed? Mark this point on the image. 2. A pendulum consists of a weight that is suspended from a pivot. At what point will the pendulum below move fastest? Mark this point on the image. 3. What do these two situations have in common? Gizmo Warm-up Objects have several types of energy. Potential energy depends on an object s position or shape. Kinetic energy is the energy of movement. The Energy of a Pendulum Gizmo allows you to explore how the amounts of these types of energy change for a pendulum in motion. 1. On the DESCRIPTION pane, change the initial angle (θ) to 40 degrees. Click Play ( ). How does the velocity (speed and direction) of the pendulum change as it swings from right to left? 2. On the image at right, mark the point where the pendulum swings fastest with an X. Then, circle the two points where the velocity is zero.
4 Activity A: Potential and kinetic energy Get the Gizmo ready: Click Reset ( ). Check that m is 0.5 kg, L is 2.0 m, g is 9.8 m/s 2, and θ is 40 degrees. Introduction: An object that is a certain height (h) above the ground has the potential to do work, and therefore has potential energy. This type of potential energy is called gravitational potential energy (GPE, or PE for short). The unit of energy is the joule (J). Question: How are potential and kinetic energy related? 1. Observe: Select the BAR CHART tab. Click Play and observe. What do you notice about the gravitational potential energy (PE), kinetic energy (KE), and total energy (TE)? 2. Measure: Click Reset. Turn on Show numerical values. A. What is the gravitational potential energy? B. What is the kinetic energy? C. What is the total energy? 3. Measure: Click Play, and then try to click Pause ( ) when the pendulum is in the middle of its swing. (This might require several tries.) A. What is the gravitational potential energy now? B. What is the kinetic energy now? C. What is the total energy? 4. Analyze: At any given time, what can you say about the total energy of the pendulum? This illustrates the principle of conservation of energy. In a closed system, energy can be converted from one form to another, but the total amount of energy remains the same. (Activity A continued on next page)
5 Activity A (continued from previous page) 5. Interpret: Click Reset. Select the GRAPH tab and turn on the PE and KE checkboxes. Click Play, wait about 4 seconds, and then click Pause. What is the relationship between potential and kinetic energy? 6. Match: The graph below shows the potential and kinetic energy curves for a pendulum. Label each pendulum image with the corresponding letter on the graph (A, B, or C). 7. Apply: Suppose a pendulum starts with a potential energy of 100 J. Assuming the pendulum has a height of 0 m at the bottom of its swing, what is its maximum kinetic energy? Explain.
6 Activity B: Calculating potential energy Get the Gizmo ready: Click Reset. Set m to 1.0 kg, L to 1.0 m, and g to 1.0 m/s 2. (Note: You can set the slider values directly by entering values into the text boxes.) Set θ to 0 degrees. Question: How is gravitational potential energy calculated? 1. Observe: Select the BAR CHART tab, and check that Show numerical values is on. What is the potential energy of the pendulum? 2. Gather data: Record the potential energy of the pendulum for each of the following sets of values for m, L, and g. Record the height (h) of the pendulum as well. (Because the pendulum s pivot is 2 m above the ground, the height is equal to 2 meters L meters.) m (kg) L (m) h (m) g (m/s 2 ) PE (J) 0.5 kg 1.0 m 6.0 m/s kg 1.2 m 2.0 m/s kg 1.1 m 1.0 m/s kg 1.5 m 3.0 m/s 2 3. Find a pattern: What is the relationship between the potential energy of a pendulum and the values for mass (m), height (h), and gravitational acceleration (g)? 4. Make a rule: Write an expression for potential energy based on m, h, and g. Test your expression using the Gizmo. PE = 5. Apply: What is the potential energy of a pendulum with a mass of 0.7 kg, a height of 0.3 m, and a value of g equal to 9.8 m/s 2? Check your answer using the Gizmo. (Hint: Set the length of the pendulum to 1.7 m.)
7 Activity C: Kinetic energy and velocity Get the Gizmo ready: Select the DESCRIPTION tab. Set m to 1.0 kg, L to 1.3 m, g to 1.0 m/s 2, and θ to 40 degrees. Question: How is potential energy converted to kinetic energy? 1. Observe: Select the BAR CHART tab, and check that Show numerical values is on. A. What is the height of the pendulum? B. What is the potential energy of the pendulum? C. What is the kinetic energy of the pendulum? 2. Observe: Click Play, and then click Pause when the pendulum is at the bottom of its swing. A. What is the approximate height of the pendulum now? B. What is the potential energy of the pendulum? C. What is the kinetic energy of the pendulum? 3. Calculate: The formula for kinetic energy is as follows: KE 1 mv 2 2 Based on this formula, what is the velocity (v) of the pendulum at the bottom of its swing? Show your work. Velocity = 4. Apply: Click Reset. Set m to 1.0 kg, L to 2.0 m, g to 9.8 m/s 2, and θ to 40 degrees. What is the maximum velocity of this pendulum? Show your work. (Hint: The exact height of the pendulum is now m.) Velocity =
