  • Waterjet And Smoothed Particle Hydrodynamics

    Particle (steel and spherical particles) waterjet is a new type of waterjet that can effectively break rock and other materials. In this study, simulation combined with experimental method was conducted to optimize the jet parameters (i. e., velocity, water pressure, impact time, concentration, diameter, and standoff distance) for modeling the rock breaking performance of a particle waterjet. In particular, the changes in the rock and particle properties after the impact were analyzed based on…

  • The Effect Of Distance On Acceleration Of Motion

    A ball, and a feather dropped at the same height will hit the ground at the same time when placed in a vacuum space. This is because acceleration of motion is the same for both object, and in this experiment, we are going to calculate accelerated motion using inclined planes. In this experiment, we will see whether “distance traveled is directly proportional to the square of the time”, and “if speed of a falling object depend only on the height from which it falls”. This experiment will give us…

  • Linear Equations Lab Report

    to find the x and y position equations are as follows: position-x= mx+b and position-y= g/2(x^2)+vel(x)+in. M equals the slope of an equation which can be found by taking the derivative of the x equation, which we have done, and vel represents the velocity of the equation. g/2 represents the acceleration affecting the equation, which is gravity, and in represents the distance from the vertex to the origin. Notice that gravity had to be converted in order to keep all units consistent throughout…

  • Pendulum And Spring Essay

    The position and velocity data for several oscillations was recorded A smaller amplitude oscillation was used and the amplitude and velocity data recorded until the amplitude decreased to half of its initial value. The position of the mass and the hanger was changed and the last step was repeated once more. The mass of the spring…

  • Roller Coaster Ride Essay

    hill. As a consequence, they will experience the feeling of weightlessness, free fall, huge amounts of kinetic energy, and air resistance. The drop gives you an instantaneous speed of 56 miles per hour. This is also where you reach your terminal velocity. As you are falling, you will feel as if you are only being held down by gravity, which in fact, you are.…

  • Pendulum Experiment

    INTRODUCTION Can the magnitude of gravity be found by measuring the period in relation to the length of the string of an oscillating pendulum? The aim with this lab was for us to gain a greater understanding in the area of oscillations and simple harmonic motion. Also to determine if the use of a pendulum is a good strategy for measuring the gravity. I found this experiment to be very interesting since I’ve seen and used pendulums a lot before, but I have never really reflected on why they…

  • Centripetal Acceleration Essay

    At (a), the surface is not inclined. When a vehicle moves around a bend or a corner on a flat road, it is moving in circular path. Therefore, it will experience centripetal acceleration and there must be an external force causing centripetal acceleration. As shown in the diagram, the only thing in contact with the car is the road, which is between the tyres of the vehicle and the surface of the road. Therefore, we can know that the frictional force exerted between the tyres and the road directed…

  • Paper Bullets Experiment: Data Analysis

    Paper Bullets Experiment: Data Analysis The scientific question that was investigated by the paper bullets experiment asked, “Does the width of a paper bullet affect the distance it travels when it is launched?” The hypothesis that goes along with that question is, “If a paper bullet has a larger width, then it will travel a shorter distance than a standard paper bullet with a width of 4cm.” Variables in this experiment included independent variable (width of the starting piece of paper used to…

  • Initial Velocity Lab Report

    of release and the initial velocity? Apparatus 2: What is the relationship between length of the ball catcher and the final velocity of the system? Additional question: What is the percentage error of the initial velocity calculated using momentum and kinematics? Percentage error between theoretical initial velocity and experimental initial velocity? How much energy is lost? note: the initial velocity calculated using kinematics should equal to the initial velocity calculated using…

  • Personal Velocity Character Analysis

    Personal velocity by Rebecca Miller is a series of seven short stories all in one novel. They are about seven different women, describing their personalities and how they are shaped. Each character was unique in their own way, but the background of their lives was usually the same. The three characters I liked more were Greta, Delia, and Julianne. These three women have very different basic core personalities. A core personality is are primary traits that people develop usually in their…
