Samantha Mackey 13. 2nd hour PHYSICS LAB REPORT: SPEED OF SOUND Purpose: In this lab‚ we will be doing 3 major things: 1) Collecting and organizing data to obtain resonant points in a closed pipe‚ 2) measure the length of a closed-pipe resonator‚ and 3) analyze the data to determine the speed of sound. Procedure: 1. Fill the graduated cylinder nearly to the top with water‚ with a tall glass tube open at both ends (the water level with act as the closed end). 2. Determine

Objective: Motion on an Incline with Friction The purpose of this experiment is to prove that the experimental acceleration value calculated is close to the theoretical acceleration values by finding the tension force‚ normal force‚ kinetic friction and the coefficient of kinetic force from the data collected. Theory: The forces acted on an object can be divided up into many different components depending on what the object is doing. In this experiment‚ an object is sliding up an incline plane

of a process called motion capture. Motion capture has been around since the late 1970s‚ where it was then called rotoscoping and was used by Walt Disney in the film Snow White (Sturman). To begin with‚ the term “motion capture” actually has many different names‚ such as mocap‚ performance animation‚ performance capture‚ virtual theater‚ digital puppetry‚ real-time animation‚ and the favorite among traditional key frame animators is “The Devil’s Rotoscope” (Furniss). Motion capture‚ in its most

Lab 4 Projectile Motion Sai Moua Purpose: The purpose of this lab was to define what the initial velocity of the ball when it is launched out of the pipe. Our next objective is to determine at what angle that the ball will be ejected at the maximum range. Lastly‚ we predict and confirm the range before we launch the ball at a certain angle. Theory: Projectile motion according to Dr. James S. Walker is defined as‚ “the motion of objects that are initially launched –or “projected”- and that

Physics (from Ancient Greek: φυσική (ἐπιστήμη) phusikḗ (epistḗmē) “knowledge of nature”‚ from φύσις phúsis "nature"[1][2][3]) is the natural science that involves the study of matter[4] and its motion through space and time‚ along with related concepts such as energy and force.[5] More broadly‚ it is the general analysis of nature‚ conducted in order to understand how the universe behaves.[a][6][7] Physics is one of the oldest academic disciplines‚ perhaps the oldest through its inclusion of astronomy

PDP Physics Lab Report – 01 NAME: Wang Xueqian DATE: 2014/06/21 Introduction In this experiment‚ we will investigate the relationship between the linear speed of an object and magnitude of centripetal force acting on it. We will use a stopper moving in a circle to create an upward force on the hanging mass; at equilibrium‚ the upward force on the mass will exactly equal the centripetal force.
