Center of mass

Objective: The purpose of this lab was to examine Newton 's second law by observing the relationship between force and acceleration in a friction-free environment and to illustrate the concept of mass. The experiment was conducted in such a way to reduce friction. In order to simulate this environment an air-cushioned track was set-up for the glider to ride on a pocket of air without being in contact with the metal track. In addition, this glider will have masses attached to it as well as a…

what they like to believe “follows the same pattern as a typical mass with additional elements that draw attention to the place the deceased person has in the life of the mourners and most especially, the Christian belief in resurrection” (“Preparing for a Roman Catholic Funeral”). A mass is also what Catholics refer to as a normal Sunday service. If Shipman Funeral Home decides to serve this family and provide a Catholic funeral mass some things we can be expecting to see according to the Roman…

the cynical flask’s arm. 9. Quickly pour the CaCO3 into the cynical flask, plug in the rubber stopper and start the stop watch. 10. Every 10 seconds, record the amount of gas inside the beaker. Record 11. Repeat steps 2-10m, but keep the mass of the CaCO3 the same as the first experiment. Results Time passed (sec) | Chips (cm3) | Granules (cm3) | Powder (cm3) | 10 | 0.5 | 15 | 30 | 20 | 0.5 | 30 | 50 | 30 | 0.5 | 45 | 60 | 40 | 0.5 | 60 | 70 | 50 | 1 | 72 | 75 | 60 |…

side (Farrell, 2006). The trebuchet uses Isaac Newton’s laws which are; The greater the mass of the object being accelerated the greater the amount of force needed to accelerate the object and (Pearson science ,2012). The motion of the projectile launched is parabolic and is influenced by factors such as the mass of the counter weight, the length of the pivot arm…

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…

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…
