Place the cups under the heat lamp(s). We can say that one form of energy (potential energy) is converted in another form of energy (kinetic energy). The volume is determined by measuring with a ruler and by water displacement. This was done by causing elastic collisions, inelastic collisions, and explosions of carts on a Dynamic Track. The purpose of the experiment was to find the effect of a balls drop height on its return bounce height. energy that spontaneously passes between a system and its surroundings in some way other than through work or the transfer of matter. If the compound possesses the qualification of an electrolyte, it can be identified as an ionic compound, seeing as ionic compounds are capable of conducting electricity when dissolved in water. From identifying the distance-time graph equation, the next step is to find the velocity of the set data. Accuracy is how close the average of the measured values are to the actual value. Kinematics requires the understanding of how objects move vertically and horizontally.

According to the data, on Ball- Mass 1 the 11 pound ball got an average velocity (m/s) of 3.14, the kinetic energy of 24 (J), and the average bowling points of 3. After the time has elapsed, record the actual elapsed time in the Tfinal column in Table A. next 5 minutes, while you prepare the calorimeter in the next steps. These equations are as follows: The purpose of this lab was to test the relationship between velocity, position and time. endobj The ratio of the final momentum to the initial momentum was calculated for all conditions except the explosion. PDF Lab Handout Lab 13. Kinetic Energy - static.nsta.org Why or why not. This is most likely because the reading of the return bounce was not exactly correct and neither was the drop height. Record all data in Table A, and calculate the %PDF-1.5 Understand the role of the mass in a conservation of energy situation. Lab Report: Acids and Bases. by Alondra Garza - Prezi other two cups, filling one with 100 g of wet sand and one with 100 g of dry sand. Also, to see how gravity pulls the ball down storing energy and releasing the energy as the ball hits the bottom of the ramp and to see the distance the ball travels after books are added. Overall the total energy (_____________) is conserved. in Table B. Every radioactive element has a different halflife. Final Lab Report: Solar Cookin' - Suffolk University G. Establish an initial temperature of the metal samples. mass. Therefor inelastic collisions can be defined as collisions in which kinetic energy is not conserved. In elastic collisions the objects that collide do not stick together, and both continue on with new velocities after the collision. If needed, place the calorimeter into a beaker or other secondary container to prevent wobbling. The carts were placed on the track so that the Velcro side of each cart was facing the other. Then you can change the height of by adding a .75m desk on top of the .95m table. The final condition tested was explosions. If this wasn't your finding and GPE was greater, you might have some errors in your timing for dropping the ball. There are multiple possible sources of error in this experiment. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Dry sand 100 19 63 44 Do this a few times to find an approximate horizontal distance from the base of the table to where the duck initially contacts the ground. These resources will help you complete the assignment. The fact that the kinetic energy ratio was very far from one shows that the kinetic energy is not conserved in explosions. The first step was to graph the distance-time graph from the data collected. These sensors were attached to a computer, which was running the Logger Proprogram, through a Vernier computer interface. heated aluminum wire from the hot water to the calorimeter using the tongs. Typically an ionic bond occurs between one metal and one non-metal ion. << Each object can only have a certain amount of energy and that energy is in different forms. Practice dropping the soda bottle so that the bean bag pops up straight and, can have its height measure with the meter sticks. any excess water drip off the wire sample, but make the transfer quickly so the metal Temperature is a measure of the internal energy of a system. Lesson: Types of Chemical Reactions, Project: Thermal Energy and Chemical Reactions Students apply knowledge of technological design, as well as techniques of project-based learning in order to investigate the relationship between chemical processes and the release of thermal energy. Kinetic factor refers to DGa, activation energy; while the thermodynamic factor refers to DG =G 2-G 1, the driving force. This would force the carts to repel each other and not stick together during collision. Data: m = kg Fave = N x (m )v /s Wo rk JKE % Dif enc Scoring Rubric: E6.

Covalent bonding is a root within Organic and Biochemistry that needs to be understood in order to fully understand the theories and concepts discussed in both forms of chemistry. Place an empty trimmed cup on the mass She is also certified in secondary special education, biology, and physics in Massachusetts. 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. 1. circle one There are many properties that distinguish an ionic compound from a covalent compound. Theology - yea 1. You always get 8 slices, but some of those slices might be cheese, while others might be pepperoni.
