In the volume lab, my group and I were to perform four tasks that were all related to the measurement of the volume of fluids and solids. In the first task, we had to guess and count how many drops of water it would take to equate a milliliter. Using an eyedropper, we measured how many drops it took to get a ten milliliter graduated cylinder filled with seven milliliters of water to eight, nine, and ten milliliters, After that, we had to find the average of how many drops of water it took to raise

David Chavez Arturo Huipe Chem 221B Lab January 20, 2016 Experiment 1: Introduction to Microscale (Option A) 1. Weigh a 3-mL conical vial with the screw cap and Teflon insert on a scale. Weight it to the nearest milligram (nearest 0.001 g) 2. Use the automatic pipette and get 0.500 mL of water and put it into the vial, replace the cap assembly (with the insert arranged Teflon side down), and weigh the vial a second time. 3. Find the weight of water dispensed. 4. Determine the density of water

All of last week we worked on building mousetrap cars. I briefly described them in my last blog post but on this post I will make a more detailed blog about what I struggled with and what went well for me and the whole process I went through while making this car. The first mousetrap car that I made was a total disaster. I tried to do something different from what everyone else was going, to see if I could create something that would be more successful in some aspects also because the pictures

Abstract: The purpose of this lab was to understand momentum and energy and how they are related in the event of a collision. This experiment played around with that and different mass on carts was projected to elastic and inelastic collisions. One cart would be stationary while another was plunged towards it or they were both moving. As a result the elastics final kinetic energy was pretty much equal to the initial kinetic energy. In the inelastic case the final kinetic energy is normally less

For each mass, there is a force on a spring that acts on it from both left and right side of the masses. The following list of equations, that will be written in a linear system of differential equations, represents the forces acting onto each mass: m_1 〖x_1〗^''=〖-k〗_1 x_1+k_2 (x_2-x_1 ) m_2 x_2^''=〖-k〗_2 (x_2-x_1 )+k_3 (x_3-x_2) m_3 x_3''=-k_3 (x_3-x_2 )-k_4 x_3 m_1 〖x_1〗^''=x_1 〖(-k〗_1-k_2)+x_2 (k_2)

to the set accuracy distance of 2.2 meters. Removing part of the counterweight did result in a shorter launch distance that was closer to the 2.2 meter goal than our first two launches. Newton’s second law of motion demonstrates that adjusting the mass of the counterweight exerts a greater force. If we were to improve our trebuchet, I would add more weight to the counterweight if we were going for a greater launch

A 12” x 12” x 2” sheet of EverFlex V34 Medium-Firm, EverFlex V44 Firm, DuraFlex D30 Medium-Firm, Latex Foam and Memory Foam were tested to see which was the best when it came to weight distribution. First, a sheet foam was placed on a blank table, followed by the Sensor Edge pressure sensor on top of it. The sensor was carefully placed so that the edges were not tucked under the foam, but were laid out. Then, a Barbie was placed in the center of the sensor, without letting any part of the doll fall

II. Physics A. Laws: All three of Newton’s are applied, movements are tracked. The efforts needed to perform those movements depend on the mass of the person wearing the fitness watch the Garmin Fenix 5, the terrain they are on, traveling uphill versus downhill, head wind or tail wind all effect the velocity and momentum that the wearer have. The runner will continue in motion at the same rate unless an opposing force acts upon them, these forces are not necessarily objects, like wise the wearer

After carrying out the practical it is evident that the ping pong ball had a higher rebound than the tennis ball, bouncing 2.35cm higher when comparing the calculated average rebound height which proves the hypothesis that the tennis ball will bounce higher than the ping pong ball incorrect. The tennis ball’s rebound height ranged from 61cm to 64cm with 3cm difference. The ping pong ball rebound height difference is also 3cm as its height ranged from 63cm to 66cm. The greatest forced that is acting
