Mass Effect 2

Name: Institution: Course: Instructor: Date of Submission: Pendulum and spring Abstract In this lab, two systems namely a pendulum and a spring that exhibit simple harmonic motion were studied. The systems were subjected to a mass of known weight and allowed to oscillate. Afterwards, the period of each was determined. In addition, the harmonic properties in the systems and their limiting factors were determined through quantitative calculations. Introduction Any system that exhibits back and…

the role played by each part of the body if we were to analyze the dynamics of an extended object. However, there is one point, associated with the geometric mean center of the mass distribution of an extended system, known as the center of mass, always behaves like a point particle as if all the external forces, and the mass of the entire system, are on that point. In this view, all the…

object or tool, a Master of Science Thesis Jijju Thomas 2 Introduction stable stance is found with all the points of contact considered. When producing a pushing force, a human’s stance often consists of either one foot or both feet displaced some distance from the object being pushed. The two stances are called the ‘feet-apart’ pose and the ‘feet- together’ pose as shown in Figure 1-1. An angled-body posture, by displacing the center of mass both forward and downward, can help reduce the…

Energy equation Equation of energy for an electrically conducting, viscous incompressible fluid is ρC_P [∂T/∂t+(q ̅.∇)T]=K∇^2 T+μ(1+1/γ) (1.3) where =2[(∂u/∂x)^2+(∂v/∂y)^2+(∂w/∂z)^2 ]+(∂v/∂x+∂u/∂y)^2+(∂w/∂y+∂v/∂z)^2+(∂u/∂z+∂w/∂x)^2 is the dissipation function which represents the time rate at which energy is being dissipated per unit volume through the action of viscosity. Here, u,v and w are the velocity components of the…

Introduction: The purpose of this lab is to help students gain a better understanding of physical concepts such as work (which occurs when an applied force moves an object.) torque (defined as a twisting force), energy and rotational inertia (an object's resistance to rotation). Experimental Design: My group’s testable question throughout the mousetrap car experiment was: If we add and subtract factors such as material, weight and shape, from the wheels of our car, how will it affect the…

During the course of this practical, the different factors of a pendulum will be investigated. A pendulum is a mass held from a fixed point so it is able to swing freely, the mass swings back and forth in an arc. The formula for finding the period of a certain pendulum lies in the change of the length of string suspending the mass, and the force due to gravity where the pendulum is being used. This relationship is shown in the equationT=2π√( L/g) (Sean, 2010), as the length of the string…

However, in reality, it is likely that the bounce height will increase less than the initial height, because air resistance will not be negligible. As the initial height increases, the effect of air resistance will also increase, meaning that the bounce height will increase less than it would without the effect of air resistance. Therefore, it is predicted that the coefficient of restitution will decrease slightly as the initial height of the tennis ball…

Gravity. Gravity causes all objects in Freefall to accelerate downwards at the same rate, regardless of the object’s mass. On Earth, acceleration due to gravity is constant of 9.81m/s^2. Therefore on Earth when air resistance is not present, all objects fall at the same acceleration of 9.81m/s^2. However, on the planet Vela Rani, the value of acceleration due to gravity is 15.3m/s^2. Therefore, all objects within the gravitational field will fall faster than on earth due to the increase in force…

cortisol production increases, the latter being shown to oppose the retention of lean mass while also inhibiting the appetite-suppressing effect of leptin (Trexler 2014). Illustrating the significance of these hormones, a 2012 study proposed endocrine factors to be predictors of the success or failure of weight loss attempts, as lower ghrelin and higher leptin baseline levels were anticipatory of lower body mass in female subjects following a twelve-week calorically restricted diet (Labayen…

cylinder with the piston which pumps the water. Oscillation of the pendulum is maintained by periodical action of the human arm. Oscillation period of the pendulum is twice bigger than the period of the lever oscillation. Piston of the pump has reverse effect on the lever and damps its oscillation. Damping of the lever motion causes damping of the pendulum, but the work of the force damping the pendulum is less than the work of the forces which damp the lever. Equilibrium position of the lever…
