Experiment 9: THE TANGENT GALVANOMETER; PURPOSE: In this experiment we will measure the magnitude of the horizontal component of the Earth’s Magnetic field by the use of an instrument called a tangent galvanometer. INTRODUCTION: A tangent galvanometer consists of a number of turns of copper wire wound on a hoop. At the center of the hoop a compass is mounted. When a direct current flows through the wires‚ a magnetic field is induced in the space surrounding the loops of

Experiment 1: Simple Harmonic Motion Dominic Stone Lab Partner: Andrew Lugliani January 9‚ 2012 Physics 132 Lab Section 13 Theory For this experiment we investigated and learned about simple harmonic motion. To do this we hung and measured different masses on a spring-mass system to calculate the force constant k. Simple harmonic motion is a special type of periodic motion. It is best described as an oscillation motion that causes an object to move back-and-forth in response to

The lesson is divided into 3 labs that can be completed in any order. After labs have been completed‚ facilitate a class discussion where students summarize and compare findings and relate how their findings support (or refute) Newton’s Laws of Motion LAB 1: How fast can it go? Put one car at the top of the ramp and let it roll down. Use a stopwatch to record the time the car rolled. Use this information to calculate the acceleration of the car. Measure the distance the car rolled using the

The moment of inertia is a measure of an object’s resistance to changes in its rotation. It must be very specific to the chosen axis of rotation. Also‚ it is specific to the mass and shape of the object‚ including the way that is mass is distributed in the object. Moment of inertia is usually quantified in kgm2. An object’s where the mass is concentrated very close to the center of axis of rotation will be easier to spin than an object of identical mass with the mass concentrated far from the axis

The length d from the edge of the frame to the thread should be 0.24m. iii) Measure and record the value of d. iv) Determine the percentage uncertainty in this value of d. v) Gently displace the pendulum so that it performs small oscillations in a vertical plane perpendicular to the plate. vi) Make and record measurements to determine the period T of these oscillations. vii) Adjust the position of the plate to give

Then analyze and interpret back and forth motion in kinematics graphs. Use kinematic graphs to catalog objects that exhibit similar motion. PRELIMINARY QUESTIONS: Finding the average velocity Do any of the four objects listed above move in similar ways? If so

DESCRIPTION The Centripetal Acceleration lab consists of using a pendulum bob swinging continuously. This will help see the F_max(tension) and F_(mean )(weight of the pendulum)‚ net force (N) and v_mean(velocity). RESULTS When starting the lab the first thing to do is to measure the cylinder properties (the bob) in table one. The measurements were: diameter (D) is .0815m‚ height (H) is .025 m‚ mass is .06591 kg‚ and the 〖Weight〗_theory W is .645918 Mg‚N. Second thing to do is to launch from

The smallest division of vernier scale is called the least count of vernier caliper. It may be different for different vernier calipers (and other measuring instruments). In order to measure length

The point where the centripetal acceleration is provided completely by gravity is when the centripetal acceleration is equal to the gravity. This happens at the point where h=r/2. As the truck moves from point A to point B‚ it would have decreased in height by r. Applying this again to our equation‚ we get; Hence‚ Using this in our g-force equation‚ we get; And so the rider experiences an additional 2g of centripetal force from that experienced at the top. Later‚ as the tuck moves to point
