Conclusion:
To conclude, the hypothesis was proven right. Syrup, the most viscous liquid, caused the metal ball to have the slowest time. The strong frictional force that acted against the ball, caused the ball to have the slowest time. For example, water had the smallest frictional force which was 8.73 × 10-4 N, but syrup had a frictional force of 2.9x10-3 N and the time it took the ball to fall through the water was .16 s and for syrup was 5.03 s, which took longer than water .Therefore, the ideal frictional property that the U.S. Swimming Masters swimming coaches would like in the innovative liquid to have is syrup.
Improvements:
A weakness or limitation in the process of the experiment could be that the metal mall probably did not start initially at 0 ms-, because the rim of the graduated cylinder reached a height of .011 m above the surface of the liquid. Therefore, the ball did not start falling in the liquids with an initial velocity of 0 ms-, which could have affected the results. Ways that this issue could be fixed is by filling the cylinder to the rim and re-measuring that distance to 0 mL. In addition, there could have been a few human errors in measuring. Since data recording relied on the physics app, there could also have been some inaccuracy while using it.
Data Collection:
6. Open the Video Physics
7. Take a video of the metal ball falling in water for three trials and make sure the camera is parallel to the side of the graduated cylinder with the scale

Dependent Variable:
• The dependent variables in the experiment are the time and frictional force.
Controlled Variables:
• Gravity (9.81 ms-2)
• Copper Coated Premium BB (0.0003 ± .00001 kg)
• The viscous liquids (water, syrup, vegetable oil and olive oil)
• Ruler
• Scale
• Graduated Cylinder (100 ± .5 mL)
Method: In this experiment there will be a 0.0003 ± .00001 kg metal ball that will be passing through different viscous liquids. Using the time, one will be able to find the average final velocity and acceleration. After those two variables are found, one will be about to find the applied force metal ball placed against the liquid to pass through. Then, the force of the metal ball free falling with no air resistance will be subtracted by the applied force to find the friction of the viscous liquids.
Materials:
The goal of this experiment is to develop a theory, which allows us to understand the motion of a marble.
Also we might have been shaking the test tubes at different speed which may have caused a greater number of bubbles to be released. Overall I felt that the experiment was accurate and reliable and there was not much that could have been changed on it.
The Purpose of this lab is to use the impulse and momentum concepts to explain what happens when the eggs are dropped onto various objects.
Planning Firstly here is a list of equipment I used. Boiling tubes Weighing scales Knife Paper towels 100% solution 0% solution (distilled water) measuring beakers potato chips Cork borer. We planned to start our experiment by doing some preliminary work. We planned to set up our experiment in the following way.
In this experiment, there were several objectives. First, this lab was designed to determine the difference, if any, between the densities of Coke and Diet Coke. It was designed to evaluate the accuracy and precision of several lab equipment measurements. This lab was also designed to be an introduction to the LabQuest Data and the Logger Pro data analysis database. Random, systematic, and gross errors are errors made during experiments that can have significant effects to the results. Random errors do not really have a specific cause, but still causes a few of the measurements to either be a little high or a little low. Systematic errors occur when there are limitations or mistakes on lab equipment or lab procedures. These kinds of errors cause measurements to be either be always high or always low. The last kind of error is gross errors. Gross errors occur when machines or equipment fail completely. However, gross errors usually occur due to a personal mistake. For this experiment, the number of significant figures is very important and depends on the equipment being used. When using the volumetric pipette and burette, the measurements are rounded to the hundredth place while in a graduated cylinder, it is rounded to the tenth place.
Start with the hot water and first measure the temperature. Record it. 8. Then pour 40 ml into the beaker. You can measure how much water was used by looking at the meniscus.
To investigate the affect the material of a ball has on the bounce height of that ball where the drop height (gravitational potential energy), temperature, location, ball, and air pressure of the ball are kept constant.
== Refer to, Chemistry Lab #1 – What’s the substance? I didn’t change most materials when I did this experiment, but I added 4 materials, which are: * 5 test tubes * 2 stoppers * 1 large piece of paper And I deleted 1 material, which is: * Spatula Methods = == ==
Presently scientist are conducting research to help people gain new techniques in swimming. While scientists continue research for new swimming techniques, they must start with early techniques of swimming as a sport and part of life. Learning how to swim is not easy. However, swimming is physics. There are laws, buoyancy, drags, and motions. To become a good swimmer one should take initiative to learn how certain techniques evolved and take an active approach into applying these physics into their own strokes. This report will state a brief summary of the physics of swimming and its mechanics and then continue by describing the technique of the freestyle and backstrokes.
There is also the potential of human error within this experiment for example finding the meniscus is important to get an accurate amount using the graduated pipettes and burettes. There is a possibility that at one point in the experiment a chemical was measured inaccurately affecting the results. To resolve this, the experiment should have been repeated three times.

On a more scientific note I am interested in mechanics of fluids. This interest was enforced last year when I had the opportunity to attend a lecture on fluid mechanics at P&G. At the conference I greatly expanded my knowledge regarding the physical aspect of fluids and their properties. In last year's AS course we have met a topic in this field. I will be applying ideas and knowledge gathered from last year for this investigation.

Projectile motion is used in our daily lives, from war, to the path of the water in the water fountain, to sports. When using a water fountain or hose, projectile motion can be used to describe the path and motion of the water. This technology was created by finding the angle at which the water would come out at a maximum height and the person using it would be able to drink it without leaning over too much. These types of projectile motion will be further explored and analyzed in this assessment.
