HELP ASAP ITS 8th GRADE SCIENCE BUT IT DOESN'T HAVE THAT OPTION The graph shows the kinetic energy (KE) and potential energy (PE) of a bouncing ball o ver a period of 9 seconds. descriptions of the heat gained by water, wet sand, and dry sand that you have made by This friction converts some of the energy of the ball into heat, making the value measured for KE less than expected. 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. bundle of steel wire. Measure the mass of the water in the calorimeter. The carts were placed on the track so that the Velcro side of each cart was facing the other. To begin the lab a Vernier Dynamic Track was set up and leveled on a table. The initial velocity of the standard cart and the final velocity of both carts, moving together as one, were measured using the Photogate sensors.

The analysis of the results of this experiment shows that momentum was conserved in all types of collisions. As the height _________ the GPE will decrease while its kinetic energy increases. Inquiry Lab Kinetic Energy and Motion Read the entire activity on pages 180 and 181 of the textbook. 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. When does the ball have the most kinetic energy? After the lab was over this data was analyzed using the equations above to give the following values. Two carts, that had already been weighed, were placed in the track. 3. 2 0 obj
in the water. '%30r85. Energy is never created or destroyed, only converted between forms - this is known as the law of conservation of energy. with 300 mL of room temperature, add water to the calorimeter until you read 300 g of 2.

What was determined to be true was that the potential energy was larger than the kinetic. 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. Understand the role of the mass in a conservation of energy situation. This change and transfer is mediated by one or many forces.Dropping an item from specific heights and weights to see what the kinetic energy measures for each was fun. Energy that exists by virtue of an object's motion is called the Kinetic Energy. Momentum cannot be lost in a collision. energy in the earth system part 1 unit 4 heat and. This allows for a more accurate measurement. 1 0 obj
These sensors were attached to a computer, which was running the Logger, program, through a Vernier computer interface. There's also a Tips and Tricks folder that needs more added to it, so if you have any of those to give, it would be appreciated. Therefor elastic collisions can be defined as collisions in which kinetic energy is conserved. The Logger. f. Make a hypothesis about which set of sample mass, the 200 g or 100 g, will heat up the h.wTU#5SQ-fr"hul,h1,fXE1"Z3Z|6@'ru` 9Zpt%2{F&Q"N#/{]B; y&p*.0~A!mGTFeOnHtH_\02w4r7D\x/heDz0*q[P. The first step was to graph the distance-time graph from the data collected. The hypothesis that if it the ball was dropped from a higher drop points, it would have a greater bounce height was supported. You wouldn't be wrong, but every object, moving or stationary, has energy. Additionally, the lab will teach how to properly use Dynamic Tracks, which will be a valuable lab skill in the future. SOLUTION: Kinetic Energy Student Guide Lab Report - Studypool Key points: When you leave the EdgyBot to do work by itself, you need to stay on the same tab. 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. c. Coil the wire around a pencil or other object, or fold the wire tightly to create a more If you want the answer key, you can dm me or you can comment so it'll get more people to see it. Measure the height from which you'll be dropping your tennis ball. While the slope of the linear trend line was 4084.798, the actual mass of the van and Mr. Simmons combined was 2450 kg. In this lab it was found that momentum was conserved in each of the situations above. endobj

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. hd At the __________ the potential energy is considered equal. 5) 5 mL of sugar was added to the solution and a balloon was placed over the opening of the bottle to minimize the loss of any gas from the system. When the standard cart reached the plunger cart they collided, stuck together, and continued down the track with a new velocity. xnd r `v^5CHQTuUs3$"@NlvU|ss?t%DnVRB\V?D?vXo"Kb-dYoLD7ee~QNm4V]K = w]SYx,yR"LT5IF}D7UGZM]|hSaZma zmQG_U8H#"hP NwZGjvm2_'iT0jU!nehu#K"BF(C9B:6^fiO-ZzVCW^DF;l*=)q`D-ef1FG2LmQ}WBzP+/]3G^5LL2 m)f3d#Xa.

for the other two cups, filling one with 200 g of wet sand and one with 200 g of dry sand. We wrote down our data to prove that speed, height, and mass affect kinetic energy. In inelastic collisions kinetic energy was not conserved because the value of the ratio of initial and final kinetic energy was not close to one. In elastic collisions kinetic energy was always conserved. - Explore the relationship between kinetic and gravitational energies, The m is the mass of the object and v is the velocity of the object in motion. In each calculation below the initial momentum is calculated using the following formula. Acids and bases are encountered frequently both in chemistry and in everyday living. Vocabulary Words .

PDF Lecture 1: Kinetics vs. Thermodynamics: different but related The values of the velocities were shown on the Logger. Overall the __________ (kinetic plus potential) is conserved. If you have access to a supervised laboratory, do Part A. You might think there is no friction in the air, but air is actually made up of millions of tiny gas molecules. The raw data readings for the elastic collisions are shown below. Cross), Forecasting, Time Series, and Regression (Richard T. O'Connell; Anne B.
