Lab #2 Acceleration Mikaila Richards Lab partner: Christina Langone October 17th, 20th, 22nd, 2014 I. Introduction: The purpose of this lab was to design and perform an experiment that proves the hypothesis: An object in free fall moves with constant acceleration. Then determine a value of the acceleration in m/s⌃2. II. Equipment and Materials: * Gravity drop apparatus * Metal ball * Micrometer with the uncertainty of ± 0.1mm * Infrared light timers with an uncertainty of ± 0.0001s III.
The materials needed for this experiment will be a ball, a meter long ramp, tape, a protractor, and stopwatch. For the first step you will set up the incline of the ramp at a 10° angle. Then you will mark, with tape, six points on the one meter ramp that are equidistant from one another. Next, using a stopwatch, you will roll the ball from each point three times each. After all the trials are completed for the six distances, find the average time it took the ball to reach the end from each point.
Force Fields Summary Response In Michio Kaku’s article “Force Fields”, he explains how a force field can deflect laser beams. Throughout out his article Kaku shows that future science might be able to provide the same technology as science fiction TV shows such as Star Trek because he believes that science would overcome issues of limited technology. In order for force field function correctly he suggests that there has to have three layers. The outer layer is high temperature plasma created by supercharged plasma window. The middle layer is a group of laser beams.
In the other, aluminum leftovers, the activity series was used to understand how and why the reaction took place and stoichiometry was used to predict the amount of aluminum that should have reacted in the following equation: 3CuCl2 * 2H2O (aq) + 2Al (s) 2AlCl3 (aq) + 3Cu (s) + 6H2O Stoichiometry’s importance in the laboratory is well defined in the results of the previously mentioned experiments.

Moments Of Inertia Abstract: Through experimentation the principles of inertia are observed. Inertia is the resistance to changes in state of rotational motion. It depends on the mass of the object being rotated and its shape and size, along with the center of gravity. Initially, the inertia caused by the rotating apparatus must be found. If a string is attached around the circular apparatus with a pulley with weight attached then it would normally fall at the rate of gravity (9.8 m/s^2).
Jessica Yan Rick St. Denis, Tyler Wiseman 13 September 2012 Projectile Motion: Ball in the Bin Purpose: The purpose of the experiment is to determine the velocity of a ball launched from the Projectile Launcher device, and then to use that velocity to find where on the floor the ball will land given a specific angle. Theory: Two-dimensional motion is as it sounds, made of the two components of Vertical velocity and Horizontal Velocity. Horizontal Motion can be described as constant, neglecting air resistance, and Vertical Motion is characterized by the acceleration of gravity pulling at 9.8m/s². In this particular experiment, the total velocity will be split into the two components in order to find the time in the air, and horizontal distance from the launcher. The motion of these components can be described as d=vt for constant horizontal motion, and d=1/2at² + Vit.
Procedure 3: The Compound Pendulum The aim of this experiment is to determine the value of the acceleration due to gravity by measuring the period of oscillation of the pendulum when suspended from different distances from its centre of mass. A pendulum consisting of any swinging rigid body which is free to rotate about a fixed horizontal axis is called a compound pendulum. This experiment had to be carried out at Glasgow University as the required equipment was not available at school. Procedure 1) The pendulum was balanced on a large brass knife edge to determine the position of the centre of mass of the pendulum. 2) The larger moveable knife edge was then clamped to the pendulum, at a small distance (1cm) above the centre of mass.
Uncertainty Lab By: Billy Liapis Lab Group: Celina Bozoiam, Guadalupe Martinez, Suriyah Figueroa Physics ¾ B Experiment Date: September 12, 2014 Write-Up Date: September 21,2014 Introduction: The purpose of this whole lab is to get you used to making measurements. You’ll be measuring mass, time, and length. Besides learning some basic measurement techniques, you must realize that measurements always have some uncertainty in the values. When you make a measurement (x), you must estimate, or estimate, the absolute certainty in your measurement. This number is based on how well you think that you could make the measurement.
Once the results are found you can calculate the percent error of the uncertainty values. The uncertainty value is the acceleration of the ball falling down. That value will be compared to the gravity value to see how closely related they are. Introduction The formal lab “Uniform Acceleration”, studies uniform acceleration by rolling a ball down a ramp and dropping an object to calculate its acceleration. Also this lab teaches about measurement uncertainty can be calculated using the percent error equation.
