Velocity

This is because the calculation that relates velocity to the initial height of the ball requires constant acceleration, and so assumes that air resistance is negligible. By disregarding air resistance, it would be expected that the initial height of the tennis ball would not influence COR. This is because…

swim towards sugar, amino acids, pyrimidines and electron acceptors. Thus, the goal of this experiment was to determine whether E. coli has a direct motion or random motion when a chemoattractant (glucose) was present. This was done by observing the velocity before and after the chemoattractant and by making Log-Log Plot. Theoretical Chemotaxis refers to the ability of organisms to move in response to the presence of a chemical. The movement of organisms could be either attractant in the…

temperature at different depth along the year was evaluated to determine the optimum depth for high performance and low economical cost. Then the effect of structural factors including the pipe length and inner diameter, in addition the effect of air velocity passing through the pipe on the performance were studied. The air temperature at the inlet of EAHE was selected fixed at 40 ℃. It is fixed at this value because the average maximum temperature for the selected rejoin is about 40 ℃. The pipe…

The Bernoulli’s law suggests that as the pressure will decrease as the velocity increases in a horizontal pipe (PHYS101 Lab Manual, p22, 2017). The continuity equation also suggests similar theory that the velocity of the fluid will increases as the diameter decreases of a pipe according to PHYS101 Lab Manual, p22, 2017. Though, both equations suggestion are very similar, they are however not…

how many of us can say we are familiar with the math behind this theory? To refresh your memory, Bernoulli’s Principle states that the pressure of a fluid decreases in areas where the flow velocity increases. Imagine…

pitching deals with the strength someone has to be a good pitcher you have to understand the physics and the force behind the actual pitch. In pitching you will need to know about the physics the human body even just pitching in general and speed and velocity. Physics play a very important role in baseball especially in the pitching aspect of the game. Albert Einstein created physics way back in the like 1700’s,…

The visit to the LA’s space shuttle highlighted the story that began in a small town of Palmdale, an hour drive from Los Angeles where a space shuttle was built in a galaxy called the Milky-Way. The space shuttle flew over 100 million miles and was in the outer space for over one year of its lifetime. The dynamic shuttle finally retired to its sunny hometown and continues to delight and educate school children. The Endeavor made its final historic flight in 2015 followed by a breathtaking road…

until the free stream velocity in the test section of the wind tunnel reaches 100 ft/s. For the free stream velocity to reach 100 ft/s, the rpm setting of the frequency control should be approximately 1100 rpm. Please be aware that the rpm setting for this experiment should never exceed 1500 rpm for this lab. Should the free stream velocity reaches 100 ft/s, revolve the AOA control handle until the AOA indicator shows -6 degrees. After making sure that the free stream velocity is not changed due…

is used to show the moment of contact which is what I am talking about). In terms of the physics in the photo. The focus of this paper will be on the energy transfer from the bat to the ball, which causes the ball to reverse directions, increase velocity, and create a launch angle to potentially be a homerun. Physics in baseball is very complicated, where there are many things before during and after the swing occur, but the focus will be the moment of impact in order to stay compact. The…

depends on the velocity of the fluid. Laminar flow could be determined when the filament appeared as a straight line that passed down the whole length of the tube that occurs at low densities. When the filament found to be fluctuating in water, it is considered as transitional flow due to its velocity at intermediate. Furthermore, turbulent flow could be identified when the filament mixed with the surrounding water randomly after passing a little way along the pipe at high velocities. The type…
