In our lab, some pairs would start and stop in order to remain at the correct number of pounds on the vehicle; therefore, the car had inconsistent acceleration and the data did not accurately reflect the constant rate. I would definitely recommend Study.com to my colleagues. The fact that the kinetic energy ratio was very close to one shows that the kinetic energy is conserved in elastic collisions. Using the kinetic energy equation. Concluding that in my Game 1 the velocity of the masses of the bowling balls decreased when the bowling balls were heavier and that the kinetic energy was lower as the mass increased in the bowling balls. Using the information provided in the Introduction and your observations from Part 1, hypothesize as to the type of electrolyte the following solutions would be. The initial velocity of the standard cart and the final velocity of both carts, moving together as one, were measured using the Photogate sensors. Therefor elastic collisions can be defined as collisions in which kinetic energy is conserved. Kinetic factor refers to DGa, activation energy; while the thermodynamic factor refers to DG =G 2-G 1, the driving force. I recommend using this template. The analysis of these values showed that momentum is conserved in all collisions. Every radioactive element has a different halflife. Close the lid snugly and make sure the thermometer is immersed Also make a hypothesis about which type of material will heat up the fastest. Make sure you record the mass in kilograms in your notebook. You always get 8 slices, but some of those slices might be cheese, while others might be pepperoni. The standard cart moved to a velocity of zero and was still. The conservation of momentum is a very important concept in physics. 2. This increase can be explained by the fact that the potential energy of the spring, that was holding the plunger back, was transferred to kinetic energy as the plunger was released. This rod would be used to break the photon beam in the Photogate sensor, and send a signal to the computer. Later, one piece of rock is dropped from different heights and hole made measured. The raw data readings for the elastic collisions are shown below. place the pellets in the strainer. first example, heat energy is transferred from the stove to the pot of water, and the water absorbs the heat energy and will eventually begin to boil. 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. If you added the amount of KE and heat energy together, you would get the original value for GPE because energy is conserved. One you have found this distance, focus more carefully on this position so that you can take a measurement from the edge of the table to the position where the duck initially contacted the ground. Suggested Answers 1. Record your time in your data table in seconds. This allows you to get a more accurate answer. Place the lid on the calorimeter, and insert the thermometer.
