1. Animals Experiments were carried out in adult male Wistar rats (200-225 g; 2-2.5 months old)‚ obtained from Central Animal Research Facility‚ NIMHANS‚ Bengaluru. Adult rats were group-housed (3 per cage) in a climate-controlled vivarium with a 12:12 h dark/light cycle. All animals had free access to food and drinking water except during the stress procedure or behavioral evaluation. All the experiments were performed during the light phase between 10:00 h and-14:00 h. All experiments were approved

Experiment 1: Errors‚ Uncertainties and Measurements Laboratory Report Department of Math and Physics College of Science‚ University of Santo Tomas Abstract With the use of the ruler‚ vernier caliper‚ micrometer caliper and electronic gram scale‚ the group was able to acquire different sets of measurements by measuring the sphere of unknown composition. The group then was able to compute its mean diameter‚ average deviation‚ average deviation of the mean‚ volume‚ mass and % percent

Physics 211 Experiment #4 Newton’s Second Law – Atwood’s Machine Newton’s second law (FNET = ma) can be experimentally tested with an apparatus known as an “Atwood’s Machine” (See Figure 1.) Two weights of unequal mass‚ connected by a thread‚ are draped over a pulley‚ as shown in the figure. When released‚ the larger mass accelerates downward and the smaller one accelerates upward. Figure (1a): The Atwood’s Machine‚ showing the pulley and the two masses after a run. Figure (1b): A close

Velocity Oct. 06‚ 2013 Physics 1301W‚ Professor: Hanany‚ TA: Vladimir Abstract A ball is tossed obliquely. The vectors of position and velocity are measured. The acceleration is calculated. Introduction A toy company is now making an instructional videotape on how to predict the position. Therefore‚ in order to make the prediction accurate‚ how the horizontal and vertical components of a ball’s position as it flies through the air should be understood. This experiment is to calculate functions

Physics Lab Report#8 “Solving Problem Involving Vector Addition” Name: Fei Huo Date performed: November 12‚ 2014 Period 5 Teacher: Mr. Glasel Purpose: The purpose of this lab was to solve problems that involve the vector addition. Introduction: My classmates and I were solving the equations by graphing them and/or to solve them algebraically. Each of the equations had scales and we were to use these scales for each question in graph paper. Some if the questions didn’t need to

Impulse and Momentum Lab Part I: As the first lab of the Physics 2 curriculum‚ our class completed a lab experiment that introduced us students to a new concept that would be a foundation to the future topics that we learn in this class. In this lab activity‚ we used a lab cart on a flat track to compare the collision of the cart with a force sensor with and without the plunger during different trials. The materials that we would need for this activity are a lab cart on a flat track‚ a timer

Abstract :The purpose of the experiment is to explore elastic and inelastic collisions in order to study the conservation of momentum and energy. The guided track‚ carts‚ photogates ‚ 250 g weight and picket fences were the primary components used in the procedural part of the experiment. Each experiment involved the use of the photogates and picket fences to measure the initial and final velocities of both carts when they collide. The data was collected and translated to a graphical model for further

In this experiment‚ the time it takes for a pendulum to go through a period is going to be measured. The time it takes for a pendulum to go through one period can depend on factors such as the length of the string‚ mass‚ or the degree in which the pendulum is released from (amplitude). In this experiment‚ only different masses will be used in order to prove that mass does not have an effect on the time it takes for a pendulum to go through a period. Purpose The purpose of this experiment is to determine
