Video analysis can also identify if the exercise equipment in use is advantageous or not. If the equipment being used elongates a lever arm, then that would be an advantage for a tennis or baseball player. In this lab we will analyze four different trials of a tennis serve in order to determine which of the trials had the greatest linear velocity. In addition to this, we sought out to understand why each trial had a difference in velocity. Differences may have arisen from air resistance and other environmental factors, but it we are primarily concerned with the effect that arm length has on velocity.
Main Show Tank Calculation: The main tank has a radius of 70 feet. What is the volume of the quarter-sphered sized tank? Round your answer to the nearest whole number. You must explain your answer using words, and you must show all work and calculations to receive credit. To find the volume of the quarter shaped tank you would have to use the volume of the sphere using the equation V=4/3(3.14)r^3.
After all data was collected, the equation M1V1= M2V2 was used to determine the initial concentrations of each reagent in each run. [Note: The final volume (V2) for each run was 11.0 mL or 0.011 L]. Used the volumes and given molarity concentrations illustrated in Table 1 for M1 and V1. Below, Table 2 shows the finished initial concentrations for each reagent in each of the four
I. Experimental Question/Purpose The situation being analyzed for this experiment is a cart sliding down a ramp and crashing into different mass blocks in different trials. The purpose is to see how changing the mass of an object affects how far it gets pushed by another object going at the same velocity every time. II. Procedure/Methodology For this lab, I will need a ramp with, a motion detector, a computer with Logger Pro, a measure tape or meter stick, a cart, a scale, and blocks of different masses.
Fill each cuvettes with its respective solution. Turn on the spectrophotometer, so it can warm up then calibrate it to 0% absorbance. Put the corresponding extract blank and set the spectrophotometer to 100% transmittance, then calibrate it to 540 nm. Once catechol is added in the cuvettes, make sure the solution is mixed. Place carrot cuvette in the spectrophotometer and record the resulting transmittance.
We started the treatments at 1:45 and ended at 2:45, giving the plants an hour to fully respond to their environments. After the hour ended we retrieved our plants and weighed them using the same scale, ensuring accurate measurements. We subtracted the final weights from the initial weights, getting the change of weight in milliliters (or the milliliters of water transpired). Next, to find out the total leaf surface area for each plant, we cut off the leaves of our bean plants and then traced them onto a piece of paper. We weighed the pile of paper leaves and multiplied it by the average weight of four/five sheets of 10 by 10 centimeters squared paper, which is .8192 grams.
When the rocket was first launched, Newton’s third law took effect. The law states that “every action has an equal and opposite reaction”. Burning fuel caused the rocket to move upward, giving the rocket an equal and opposite reaction. The second law has to do with the mass of the rocket. The more weight an object has, the more force is needed to move it.
The objective was to calculate the elastic modulus for each material tested. II. Methodology To start the lab, one measures and records the height and width of the Rectangular Bar specimens (steel, aluminum, sawbones) and the diameter of the Cylindrical specimens (Birch, oak dowel, acrylic, glass) in mm using a digital caliper. To be precise, measurements are made three times,
When all the bubbles were within the center lines they would push the power button and a red laser beam would continuous circle from inside the transit. Then they would pull out a giant metal ruler (grade stake) from the back of the truck. I would watch as it was extended out from three feet to six. It was taller than me and sometimes I would hold it and try to measure myself as they grabbed the smaller computer from the yellow box. We would then walk to one of the corner stakes and attach the small computer to the grade stake as they stood it up as straight as they could inside the wooden stakes.
Many athletes, studies theirs internal and external movement and forces, in motion or in rest. Since, it helps to identify the best method to perform an action. Consequently, the study that deals with human movement, including internal and external forces that are in effect of motion or rest is called Sports Biomechanics. It is simply defined as physics applied in sports through human action. The
Coursework Equipment List • Boiling tubes (8) I will use these because this is where I will mix both the sodium carbonate and the strontium nitrate in order to form the precipitate. I need 8 because I am going to add 8 different amounts of strontium nitrate (1-8cm³) to the 8cm³of sodium carbonate. • Measuring cylinder (1) I will use this to measure the 8cm³ of sodium carbonate and the varying amounts of strontium nitrate to put into the test tubes. • Sodium Carbonate (enough to fill 8 boiling tubes with 8cm³/64cm³) This is what I will mix with the varying amounts of Strontium nitrate to form the precipitate. • Strontium Nitrate (enough to fill 8 boiling tubes with your varying amounts/36cm³) This is what I will mix with the sodium carbonate in order to form my precipitate.
In this lab experiment, I experimented with 2 different amount of borax (1g and 5g) to see if the amount of borax affects the bounce height of the ball. The ball is made up of polyvinyl acetate (school glue), borax and water. In the experiment the independent variable is borax and the dependent variable is the bounce height. I found out that borax has sort of a protective layer that creates the bounciness. Therefore, I hypothesized that the more borax that is used, it would be more bouncy, because there is more of a protective layer to it.
Start the timer and release the buggy at the same time. Make sure to mark down on the roll of paper where the buggy is at on every 1 second till it reaches 80 cm. 4.

To begin, the materials were gathered, those materials were the plates that were going to be streaked were (MAC,TSA,blood agar), the loop that is going to be used during the streaking procedure, the mixed culture that contain the unknown. This experiment was conducted in the presence of a Bunsen burner that emits an open flame. To begin flame the loop by placing it within the open flame for 10-20 seconds,
