The purpose of this lab is to test substances and to determine the physical and chemical properties of substances. 10 mL graduated cylinder - 2 g sodium chloride spoon - 2 g sodium bicarbonate conductivity apparatus distilled water in a wash bottle. These calculations illustrated the nature of momentum, and showed that momentum is always conserved. A 50 kg person falling at 10 m/s would have kinetic energy. L. Let's practice our energy types. 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. M. Compute the s pecific heat of each type of metal. 4. temperature. This rod would be used to break the photon beam in the Photogate sensor, and send a signal to the computer. Repeat steps 5 and 6 for KNO3. F. Be sure to wear protective gloves when handling all metal samples! The Logger. This is based on the equation .5mv^2=.5kx^2, where m is the mass of the duck, v is the velocity of the duck in the air, k is the spring constant of the spring in the base of the duck, and x is the displacement that the spring is compressed. This could have caused the velocities to be slower than they should have been because there was a velocity due to the friction. If you pick up a 10 N book a distance of 2 meters, how much gravitational potential energy did you . If you measure it in grams, simply divide the number by 1000 to get kilograms . These results are shown in the table below. Measure the mass of your ball on the balance. upright near the end of the lever, maybe taped against a wall.

Theology - yea The _____________________ is the change in mechanical energy, In the presence of nonconservative forces (like friction), the total mechanical energy is not conserved. A stairwell or out a window work well. Amanda has taught high school science for over 10 years. The kinetic energy before and after the system was then computed using the above kinetic energy equation. These sources of error include human error such as not keeping the acceleration constant, changing the force placed on the van, and by starting or stopping the timer late. Today's lab will elastic collision in one dimension. The energy of a moving object is called kinetic energy. - m is the mass 3. Measure 200 mL of water with the graduated cylinder and transfer it to an. any excess water drip off the wire sample, but make the transfer quickly so the metal energy that spontaneously passes between a system and its surroundings in some way other than through work or the transfer of matter. Later, one piece of rock is dropped from different heights and hole made measured. 3.

I. 1 0 obj Make sure you record the mass in kilograms in your notebook. A 50 kg ball traveling at 20 m/s would have kinetic energy. In the limit that m 2 m 1!1, v 1f! The word dichotomous comes from two Greek words that translate to "divided in two parts. This would force the carts to repel each other and not stick together during collision. 5. Kinematics requires the understanding of how objects move vertically and horizontally. This rod would be used to break the photon beam in the Photogate sensor, and send a signal to the computer. Record your time in your data table in seconds. Non-metals are stronger than metal and can get electrons easily from the metal. 2. <>>> . Water 200 20 30 9. The fact that the kinetic energy ratio was very close to one shows that the kinetic energy is conserved in elastic collisions. d. Repeat Steps 4bc for 50 g of the steel wire.

If you have access to a supervised laboratory, do Part A. ANSWER KEY . The overall goal of this activity is to provide the students with a diagram that can help them learn and memorize the different characteristics associated with chemical bonding. These ions attract each other and create an ionic bond. In your observations, include qualitative b) Swirl the thermometer slightly, and confirm that the thermometer is well within the water. Assume that the velocity of the soda bottle falling from a height of 0.8 m will, be 4 m/s. or other heating source. The standard cart moved to a velocity of zero and was still. and the calorimeter water. The desk will then be used to launch from a vertical displacement of .75m place the duck up against the book and launch it horizontally, again collecting 5 separate data points and taking the average of the. endobj place the pellets in the strainer. This is the lab data explained. She has a Master's Degree in Cellular and Molecular Physiology from Tufts Medical School and a Master's of Teaching from Simmons College. In elastic collisions kinetic energy was always conserved. b) Load the HCl and NaOH burets with HCl and NaOH solutions, respectively. The carts were placed on the track so that the Velcro side of each cart was facing the other. If students have difficulties differentiating the characteristics associated with covalent and ionic bonding, they will suffer with future topics and other branches of chemistry. Use tongs to carefully place the sample in the hot water bath. (3 points) Covalent bond, methane. So, multiply your value for height, the mass of the ball, and 10m/s2 to get GPE.

This would force the carts to repel each other and not stick together during collision. As the height decreases the GPE will decrease while its __________ increases. The hole each rock made is measured for its depth. b. <> On the other hand, the evidence shows that the 12 pound bowling ball in Ball- Mass 2 has the velocity (m/s) of 3.12, the kinetic energy of 23 (J), and the average bowling points of 4 . If needed, place the calorimeter into a beaker or other secondary container to prevent wobbling. If you want the answer key, you can dm me or you can comment so it'll get more people to see it. 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.

Dry sand 200 19 40 21. Temperature is a measure of the internal energy of a system. It should be least 4 meters so that you can measure the time easily. Place the calorimeter (no lid) on the balance and tare the balance. Overall the total energy (kinetic plus potential) is __________. These resources will help you complete the assignment. This allows you to get a more accurate answer. If this was added in to the momentum equation the ration of the final over the initial momentum would likely be much closer to one. We can say that one form of energy (potential energy) is converted in another form of energy (kinetic energy). In this experiment we will be measuring the rate of decomposition of hydrogen dioxide with the following reaction: In the first experiment, How does mass affect your game? it shows that the data on Ball- Mass 3 that the 10 pound bowling ball had the highest kinetic energy of 27(J), the greatest velocity (m/s) of 3.42, and in average it produced 4 bowling points. e. Turn on your heat lamp(s). One thing that, The purpose of the experiment was used to determine which team created a design that ultimately proved to launch the marshmallow the farthest. Some of them should be addressed in your lab report. Step 2: Note State and Appearance. 5. From identifying the distance-time graph equation, the next step is to find the velocity of the set data. Hypothesis- Answer the following question: Will an object reach the ground with more velocity than an . energy is also obvious, are known as elastic collisions. If you added the amount of KE and heat energy together, you would get the original value for GPE because energy is conserved. Place a book on top of the .95m table. KE = mv2 2 KE = 500J m = ? These equations are as follows: The purpose of this lab was to test the relationship between velocity, position and time. To unlock this lesson you must be a Study.com Member. v .
