Velocity

ideas were put into the construction of the boat. After many tests. The group had finally gotten the best time on the boat. Then the data from the tests was used to find the efficiency of the boat. Along with the rest of the data, the group found the velocity of each test. In the end, the group was able to figure out the buoyancy of the boat. The main objective for the group was, testing the boat with and without a rudder. The rudder helps the boat go straight. The first test for the boat…

Daniella Vidaurreta Physics April 8, 2015 Isaac Newton Isaac Newton, also known as one of the best mathematician and physicist of all time. Newton was born into a poor farming family and lost his father three months before being born. In 1661 Newton was sent to Cambridge University and began studying mathematics. Soon after, Cambridge University broke out in a plague causing everyone to evacuate. Through out the plague years of 1665 and 1666 Newton made the most significant discoveries…

Because of this continuous collision, the average velocity of free electrons decreases. Hence, the number of free electrons flowing from one point to another point within the conductor gets decreases. Therefore, the electric current decreases. If the voltage applied to the conductor is increased If the voltage or electric field applied to the conductor is increased, the free electrons gains large amount of kinetic energy. Hence, the velocity of the free electrons increases. When the free…

the spectrum, the .30/06 spits out a large, high-velocity round that leaves large entry and exit wounds. These traits are sought after in the pursuit of big game, such as…

perfectly inelastic collision. This is a perfectly inelastic because this collision is defined as when two objects “ stick together after the collision, meaning it follows in the same direction (Perfectly Inelastic Collisions). Other than the speeds and velocities and all of the calculations of this crash there are other aspects we need to take a look at. The question is brought up should you stop at yellow lights? According to the Highway Traffic Act, when approaching an amber light you need to…

Introduction It has been a puzzling question in fluid mechanics for quite some time as to why golf balls are designed with dimples. In the 1800’s it was discovered that a ball with scuffs in it flew through the air more consistently than a smooth golf ball.6 Manufacturers started incorporating patterns to golf balls to try and find which gave a more stable and reliable flight pattern. In the 1900’s it was determined that the strategic placement of indentations maximizes lift while minimizing…

chemical and physical levels is something that has always fascinated me. This problem, and others in the section on blood flow, offered me a chance to delve deeper into how the body works as well as transport phenomena. The problem gave us a solved velocity distribution for flow of a Casson fluid in a very narrow blood vessel. The blood in this case is treated as a two phase fluid where the phases are governed by a constitutive equation relating shear stress, viscosity, and shear rate. This…

takes the car too travel that far. Divide the change in distance it travel by the time it took to find the velocity of the car. 3. The distance from the third floor to the first is y initial and y final is zero, initial velocity is zero, and acceleration is -9.81 m/s. Using this information and the appropriate formula, time can be found. 4. The number calculated in part two is the velocity for both x initial and final, time is the number found in step three, acceleration is zero m/s, and x…

activity in the nervous system while electrically induced contractions helped differentiate between the two. Muscle fibre conduction velocity (CV) estimations outline changes in motor unit recruitment, contractile capability and sarcolemmal excitability.1 The effects of caffeine on CV have not been previously studied. These tests underpin the creation of a complete torque-velocity relationship for the muscles of the upper limb following caffeine supplementation. The methods are suitable to test…

Introduction- In theory, parachutes work because of the force of gravity. Gravity is a force of attraction between two objects, that is highly affected by size and proximity (gravity will have a stronger pull if the object are larger and close together). Gravity also differs from the mass of an object the more mass an object has the more gravity it will exert on the objects around it. When looking at really large masses, like the earth the gravitational pull becomes much greater because of its…
