Remove the aluminum wire sample and empty the calorimeter. endstream endobj 500 0 obj <>stream Each chemical compounds has a certain percentage of ionic character in its bonds and the remaining percentage as covalent bonds. In this lab we will use kinetic energy to find how much ___________ an object has. What is the diver's speed (in m/s) when he hits the water? Then you can change the height of by adding a .75m desk on top of the .95m table. After the time has elapsed, record the actual elapsed time in the Tfinal column in Table A. Overall the total energy (kinetic plus potential) is __________. Now find KE. The analysis of the results of this experiment shows that momentum was conserved in all types of collisions. Reddit and its partners use cookies and similar technologies to provide you with a better experience. At the maximum height, __, the object's GPE will be a maximum. When you are finished, submit this assignment to your teacher by the due date for full credit. The standard cart was pushed towards the plunger cart, which was at rest. To begin the lab a Vernier Dynamic Track was set up and leveled on a table. Relationship between initial and final velocities in an elastic collision . KE = mv2 2 KE = 500J m = ? An ionic bond is a type of chemical bond that occurs when one atom loses an electron to form a positive ion and the other atom gains an electron to form a negative ion, which then result in attraction. 1. Organismic Lab Lab1- Dichotomous Key Introduction A dichotomous key is a series of paired statements or questions that are used to categorize organisms with their similarities in characteristics and or structure. The Great Depression and the New Deal How did the New Deal affect minorities in the United States (African Americans, Hispanics, etc.) The balls have equal kinetic energies (k1=k2)(k_1=k_2)(k1=k2), but ball 1, which is coming from the left, is moving faster than ball 2 (v1>v2)(v_1>v_2)(v1>v2). 10 mL graduated cylinder - 2 g sodium chloride spoon - 2 g sodium bicarbonate conductivity apparatus distilled water in a wash bottle. We interpret the = sign to mean that the gravitational potential energy of the ball before it fell was converted into an exactly . PART I: Examining the Effect of Material and Mass on Thermal Energy Transfer Place the pH probe in the beaker and record the pH in the data table. Start a timer or note the time on a clock. 2. The final condition tested was explosions. Two carts, that had already been weighed, were placed in the track. Energy is never created or destroyed, only converted between forms - this is known as the law of conservation of energy. Record the equilibrium temperature in Table B. Build your own tracks, ramps, and jumps for the skater. Trim three more foam cups to half size. Use the graph to answer question 2-3. Allow the temperature to stabilize, and record this initial temperature to the nearest 0C So why would KE and GPE be different? No items have been added yet! There are many properties that distinguish an ionic compound from a covalent compound. The initial velocity of the standard cart and the final velocity of the plunger cart were the readings from the first and second Photogate sensors, respectively, on the Logger Proprogram. These values were recorded, and the procedure was repeated five additional times for a total of six readings. 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. This is most likely because the reading of the return bounce was not exactly correct and neither was the drop height. - m is the mass Whenever an object moves, some energy is converted to heat through friction. When the standard cart reached the plunger cart they collided, stuck together, and continued down the track with a new velocity. In class we learned about the principles of acceleration, time, and velocity. These results are shown in the table below. and tare for zero. I'm remaking this, so it'll be more coherent. If the speed of the object increases, its kinetic energy increases. information about whether it This is the lab data explained.

For observation 1 and 2, pour 1 cup of water into a pan and place on stove on high heat. As the height _________ the GPE will decrease while its kinetic energy increases. endobj a. Repeat Step 3a for the 200 g samples. Coil the wire f. Make a hypothesis about which set of sample mass, the 200 g or 100 g, will heat up the This rod would be used to break the photon beam in the Photogate sensor, and send a signal to the computer. Learn about conservation of energy with a skater gal! The raw data for the inelastic collisions is shown below. Measure the mass of the water in the calorimeter. Additionally the lab taught how to properly work with carts on a Dynamic Track. upright near the end of the lever, maybe taped against a wall. Therefor all the momentum from the object that is initially moving will be transferred to the other object. The hole each rock made is measured for its depth. Assume that the velocity of the soda bottle falling from a height of 0.8 m will, be 4 m/s. Textbook questions 4 and 5 of "Practice Problems," p. 179 After the lab this data was analyzed using the momentum equations above to give the following values. When the standard cart reached the plunger cart they collided, but did not stick together, and the plunger cart moved down the track. Within some problem domain, the amount of energy remains constant and energy is neither created nor destroyed. If that ball rolls down the hill however, all the GPE is converted to KE when it gets to the ground and is moving fast. 3 0 obj At the maximum height h, the object's GPE will be a _______. heated aluminum wire from the hot water to the calorimeter using the tongs. Instead, it changes from one form of energy to another. This allows for a more accurate measurement. A practices intracellular or extracellular digestion. KE = KE = 2500 J 6. 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. 3. What are the units for potential energy? next 5 minutes, while you prepare the calorimeter in the next steps. This button released the plunger, and propelled both carts down the track in opposite directions. Additionally, the lab taught how to complete momentum calculations, and the law of conservation of momentum. This will teach how to do momentum calculations for a variety of different situations where momentum is conserved - calculations that will illustrate the nature of momentum, and the fact that momentum is in fact conserved. Kinetic factor refers to DGa, activation energy; while the thermodynamic factor refers to DG =G 2-G 1, the driving force. program the reading from the first sensor was the initial velocity of the standard cart, and the reading from the second sensor was the final velocity of both carts. >> Amanda has taught high school science for over 10 years. This was calculated using the following formula. Every radioactive element has a different halflife. Vocabulary Words . Data section includes the provided table. We can say that one form of energy (potential energy) is converted in another form of energy (kinetic energy). Explore different tracks and view the kinetic energy, potential energy and friction as she moves. When collisions occur, two properties of the colliding bodies are changed or transferred: their Energy and Momentum. To answer this question, you really have to think about the moving atoms and molecules as having energy. Step 2: Note State and Appearance. Discussion: The Work/Energy Equation says "The work done on an object by the net force on it equals the object's change in kinetic energy." or, in symbols: In your observations, include qualitative This proves that momentum is conserved in collisions. . All other trademarks and copyrights are the property of their respective owners. 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. Conservation of Energy- lab handout. At the __________ the potential energy is considered equal. Lab report law of conservation of energy states that the total energy of the system remains same, and energy cannot be created or diminish, it can just. The initial velocity of the standard cart and the final velocity of both carts, moving together as one, were measured using the Photogate sensors. any higher. Open Edgenuity and enter the purchase key. The kinetic energy before and after the system was then computed using the above kinetic energy equation. This would force the carts to stick together after collision. Newton's second law says: Force equals mass times acceleration (F= m x a). A stairwell or out a window work well. Create an account to start this course today. the total energy in the system will not change. All objects have momentum, even if it is zero, and momentum cannot be lost. The values of the velocities were shown on the Logger Proprogram. Table A: The Effect of Mass or Material Type on Thermal Energy Transfer. These resources will help you complete the assignment. This would give the velocity of each cart. To do the first experiment, the work-energy theorem is used. @W Objectives (3): - Explore the relationship between kinetic and gravitational energies - Analyze the importance of kinetic energy in falling objects.
