When a force is given to an object that can move or is moving, it changes the momentum. If the change in the momentum is faster, the force involved is greater. Momentum is calculated so that mass multiplied by velocity equals to momentum. If a car is driving at a fast speed, the more force and energy it contains. Safety features of a car are put in place so that they protect the occupants’ if a crash were to occur. Isaac Newton’s Laws of…
way to find velocity was previously stated. The equation for finding or mass flow rate is as follows: mass of waterflow time, the mass of water was calculated from the 10 fluid ounces that were used in the most successful launch. The flow time was constant for all rockets tested at 0.5 seconds. The fluid ounces had to be converted to metric units as well, then were converted into units of mass. The Fgis found by taking the mass of the rocket multiplied by acceleration, in equation form it…
Background information: Breathing: They breathe oxygen through gills. Gills are respiratory organs found in aquatic organisms, which allow the Yabby to remove the oxygen from the water for respiration. Each leg has a gill attached, with the movement of the legs helping the circulation of water over these gills. There is a thin layer of exoskeleton separating the gills from the body cavity, allowing water to cover the gills without getting inside the body. Digestion: Digestive track includes…
Gaining Access Part of the reason the group chose St Stephen was because there was easy access. First and foremost it’s a public church; anyone can go and attend mass or talk to Father Ken if they want to. It’s especially easy for students to do so because it’s very close to campus and is practically all student run. Our group also had an inside connection with a member of the church which helped us to get a foot in the door. One of the member’s roommates is Catholic and goes to church every…
A fluid in which the viscous stresses taken place from its flow at all the point are linearly proportional to the rate of change in its deformation over time is called Newtonian fluid. Newtonian fluid explains the relationship between the shear rate and the shear stress is linear with the proportionality constant, which is to be referred as the coefficient of viscosity. Non-Newtonian fluid is a fluid where the properties of fluid flow are not similar with Newtonian fluid. In Newtonian fluids,…
1) What are engineering stress and strain? Answer: Engineering Stress: Engineering stress is also called nominal stress, and it is defined as the applied load divided by the original cross sectional area of the material. Engineering Strain: Engineering strain is defined as the amount of material that deforms per unit length in a tensile test. Engineering strain is also known as nominal strain. 2) In the figure below, graphically show the toughness of three class materials:…
this experiment is the length of the string of the pendulum that could be changed. Dependent variable: The dependent variable is the time period for one oscillation. Constant/ Control measures: The constants considered in this experiment are: The mass, shape, size and diameter of the bob The amplitude (angle) at which the spring is gently left to oscillate. The path in which the oscillation takes…
The gym, it feels so natural, so free, like my new second home. My words when I went to the gym for the first time. I loved the gym. I wanted to be big and strong just like the people around. Yeah I didn’t fit in quite yet but how hard can it be? They all did it, so can I. So there I went, I started my first day at the gym. As many of you can see when you look at my arms that look like spaghetti noodles or my biceps looking like a bean my gym craze stopped after that first time. I lifted…
string. The airflow was also adjusted such that the glider moves freely with no friction. A photo-gate was also placed onto the air track, and this was connected to the computer program, LoggerPro. When the experimental arrangement was completed, the mass of the glider and flag was determined. For the first trial, no additional weights were added onto the glider + flag or the hanger. The air machine was turned on, and the photo-gate was positioned such that the speed of the glider could be…
