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

Damped Harmonic Motion Erica Partner: Steven November 8‚ 2012 Abstract During this experiment‚ the effects that the size of an object had on air resistance were observed and determined. To do this‚ a spring was set up with a circular object hanging at the end. After the spring constant of 9.0312 N/m was measured‚ equations were used to determine a calculated frequency‚ that being 7.252 Hz. Four trials—each with a different sized‚ same massed object—took place where the object was pulled

Spokane‚ Washington. Viney and Fenton (1998) defined the term electrophoresis as‚ “the migration of charged particles through a static medium under the action of an applied electric field (p. 576). Just from this definition‚ it is clear that numerous physics concepts can be used to help explain why electrophoresis works. First‚ I will discuss charge and electric fields and how these principles are utilized in gel electrophoresis. This will be followed by a

Pendulum Raiyan Hassan SPH3U September 20‚ 2011 Introduction A pendulum is a device which consists of a mass attached to a string from a frictionless pivot which allows it to swing back and forth. 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

the period and the frequency of a ticker timer. Materials/Apparatus: One ticker timer One carbon paper disc One 1.5+ meter tape One test tape One stop-watch Theory: The recording timer is a device that helps you study motion‚ it is a simple electric device plugged into mains power‚ with a stylus that vibrates up and down. The stylus hits a tape that can be drawn through leads‚ and presses it onto the carbon disc below. This leaves a dot on the tape for every hit. The

ACTIVITY: THE CAT’S MEOW / MILK CO-MOTION PURPOSE: To observe the interaction of detergent with the fat of the milk and food color 1. Provide a possible explanation of phenomenon you observed based on the result of your experiment. When food color is added to milk‚ it floats because it is less dense than milk. The non-polar fat in the milk prevents the food color from spreading‚ as it cannot participate in hydrogen bonding with water. When detergent is added to milk and the food color‚ the

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.

The Relationship Involving Acceleration‚ Net Force‚ and Mass Giho Park Purpose The purpose of this lab investigation is to observe the relationship among the net force‚ mass‚ and acceleration of an object. Hypothesis/Prediction Part A If the net force increases with a constant mass‚ then the acceleration would increase‚ because the force would push the object to increase the velocity. Part B If the mass of the cart increases with a constant net force‚ then the acceleration would
