This lab consists of both a virtual and a wet lab component. You might think there is no friction in the air, but air is actually made up of millions of tiny gas molecules. Lab # – Energy Conservation Lab #7: Energy Conservation Goals: • Determine the spring constant, k, of your particular spring using a graphical method. Hypothesis (1) If the mass of an object increases, then its kinetic energy will also increase because mass and kinetic energy have a directly proportional relationship and have a linear relationship when graphed. If you measure it in grams, simply divide the number by 1000 to get kilograms. Ensure the cap is tight. Think of total energy like a pizza. You wouldn't be wrong, but every object, moving or stationary, has energy. a) Trim off the bottom half of three foam cups. Therefore a give has fewer atoms than the same mass of aluminum. Meter sticks should be. This allows for a more accurate measurement. However, for this lab we would like to describe the motion of the objects using momentum, p=mv, instead of velocity. Lab Handout Lab 13. Each section should provide an … In this case, however, the energy transfer will be from spring potential energy to translational kinetic energy, and then back to spring potential energy, and so on. Amanda holds a Masters in Science from Tufts Medical School in Cellular and Molecular Physiology. Although there will be less friction than sliding it across a rough table, it's still there. They should start immediately when you drop it and stop it exactly when it hits the ground. James Allison. You always get 8 slices, but some of those slices might be cheese, while others might be pepperoni… These results are shown in the table below. Sociology 110: Cultural Studies & Diversity in the U.S. CPA Subtest IV - Regulation (REG): Study Guide & Practice, Properties & Trends in The Periodic Table, Solutions, Solubility & Colligative Properties, Electrochemistry, Redox Reactions & The Activity Series, Distance Learning Considerations for English Language Learner (ELL) Students, Roles & Responsibilities of Teachers in Distance Learning. Group 5. Finally, compute the percentage of the ball’s initial kinetic energy that was lost when the ball collided with the pendulum arm. credit-by-exam regardless of age or education level. The second velocity you will measure is the velocity of Glider 2 as it passes through the second photo gate. What is the Difference Between Blended Learning & Distance Learning? The mass of each copper atom is larger than the mass of each aluminum atom, for example. Fill a 250 mL beaker 2/3 full with ICE and add a little water. Calculate the volume (in cm 3) of a cylinder with a measured height of 11.76 cm and a diameter of 7.22 cm. You will need the following additional items for this experiment: stopwatch (or digital timer), hot-water baths set at different temperatures (available in lab room) ,ice-water bath (obtain a bucket of ice from the stockroom), four 10-mL graduated cylinders (these must be shared with other groups; the stockroom does not have extra 10-mL cylinders to lend) Brandon High School • ENGLISH LA AP LANGUAG, Manchester Memorial High School • SCIENCE 0877/0878, Lab-Kinetic Energy-student guide (1).docx, Lab-Kinetic Energy-student guide (3).docx, Lab-Kinetic Energy-student guide (5) (2).docx. Length of Lab #6 – Work-Kinetic Energy Theorem Therefore, if the work done by a particular force appears not to be equal to the change in kinetic energy of the object, then the system should by analyzed for possible work (positive or negative) done by other forces. Assume that the velocity of the soda bottle falling from a height of 0.8 m will, be 4 m/s. Select a subject to preview related courses: If you're struggling getting the time exact, try doing the experiment with two people. Potential energy can transfer into other forms of energy like kinetic energy. Virtual Lab: first two years of college and save thousands off your degree. After completing a laboratory investigation, add your lab report and this document with an appropriately completed Laboratory Investigation Reflection worksheet to the appropriate lab folder. Call down to your partner when you're going to drop the ball and let them use the timer. If not, why do you think that happened? Mark the board at 7.5 cm from each end. Why or why not? Basically you are transferring all the kinetic energy of Glider 1 to Glider 2! Play around with the magnet, the ball bearings and the different instruments, and see what you can set up. and all you need to do is copy and paste it in the correct order and format. Since it's still and high up, the object only has GPE. 2. Learning happens in layers and levels. 1. flashcard set{{course.flashcardSetCoun > 1 ? PART I: Examining the Effect of Material and Mass on Thermal Energy Transfer Step 2: Set up samples to examine thermal energy transfer with varying material and mass. Energy is never created or destroyed, only converted between forms - this is known as the law of conservation of energy. 5. {{courseNav.course.topics.length}} chapters | We'll use a ball to measure potential energy and kinetic energy and examine how the energy is converted from one form to another as the ball falls from a high place. This friction converts some of the energy of the ball into heat, making the value measured for KE less than expected. For some, understanding physical concepts and terminologies are like slaying a dragon. Procedure. Physics Lab Report Examples & Templates. When heat is added to 58 g of copper, fewer atoms need to be put in motion . The Work-Energy Theorem presents a way of dealing with kinematic quantities in me-chanics without regard for vector direction. Each object can only have a certain amount of energy and that energy is in different forms. Stir carefully with a thermometer until the … | {{course.flashcardSetCount}} HistoricalAside It turns out that scalar quantities played an important role historically in the Services. We measured how much the object wieghed, how fast the object fell and the height at which we dropped the object. Kinetic energy (KE), the energy of movement, and gravitational potential energy (GPE), or stored energy due to height. The equation for KE is 0.5 multiplied by mass, multiplied by velocity squared: Get access risk-free for 30 days, Before you start, make a prediction: Will the GPE at the top be the same as the KE at the bottom? Think about what you already know about energy. (Read Section 7 -3 for a thorough explanation of the W ork-Kinetic Energy Theorem.) eCADEMY High School – Westside Campus 6440 Western Trails NW, Albuquerque, NM 87120 505-247-4209 Phone | 505-848-9454 Fax If you added the amount of KE and heat energy together, you would get the original value for GPE because energy is conserved. Earn Transferable Credit & Get your Degree. The kinetic energy before and after the system was then computed using the above kinetic energy equation. The equation for GPE is mass multiplied by acceleration due to gravity, multiplied by height: Acceleration due to gravity is always 9.8m/s2; however, it is acceptable to round this to 10m/s2 for easier calculating. Sciences, Culinary Arts and Personal Place an empty trimmed cup on the mass balance and tare for zero. ... Because the mass is temporarily at rest, the kinetic energy of the mass is zero at the highest and lowest points. You may scan or take pictures of hand-calculations or hand-drawn figures (such as bond graphs) to include them in the report. {{courseNav.course.mDynamicIntFields.lessonCount}} lessons Get the unbiased info you need to find the right school. The conclusion is a very important part of the formal lab report. Did your experiment follow the law of conservation of energy? Practice dropping the soda bottle so that the bean bag pops up straight and, can have its height measure with the meter sticks. The mass of the balls does not change during the collision but the _____ is transferred from one object to the other object. Then, discuss your plan with your lab TF to see if he has The total mechanical energy at those points is the sum of the elastic and gravitational potential energies. just create an account. © copyright 2003-2021 Study.com. and securely tape the cylinder to the board with the packing tape. Make sure you record the mass in kilograms in your notebook. 3. This lab will ultimately cover the Boiling Ice Water Lab and the Specific Heat of Water and Steel (page 671 in your eTextbook). Record this in your notebook. Kinetic and Potential Energy Lab In the Kinetic Enegy and Potential Energy lab we measured how much energy an object has from different heights. You can test out of the average kinetic energy of the atoms or molecules of a substance. 5.Repaet steps Data Procedure: Lentgh of time the hot water fizzled. Let's practice our energy types.
