Introduction The purpose of this section is to introduce the concepts of displacement‚ velocity‚ and acceleration. For the sake of simplicity‚ we shall restrict our attention to 1-dimensional motion. Displacement Consider a body moving in 1 dimension: e.g.‚ a train traveling down a straight railroad track‚ or a truck driving down an interstate in Kansas. Suppose that we have a team of observers who continually report the location of this body to us as time progresses. To be more exact‚ our observers

Projectile Motion You have probably watched a ball roll off a table and strike the floor. What determines where it will land? Could you predict where it will land? In this experiment‚ you will roll a ball down a ramp and determine the ball’s velocity with a pair of Photogates. You will use this information and your knowledge of physics to predict where the ball will land when it hits the floor.

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

LAW TONG &AIDEN 2013/9/23 AP PHYSICS B Mr. Moss THE LAB OF ATWOOD Procedure: The purpose of this experiment was to verify the predictions of Newton’s Law for an Atwood machine‚ a simple machine constructed by hanging two different masses and from a string passing over pulleys and observing their acceleration.. Newton’s Law predicts that the acceleration should be proportional to the difference between the masses and proportional to their sum‚ where = 9.8 m/s2 is the

Now click and drag the red ball around the screen. Make 3 observations about the blue and green arrows (also called vectors) as you drag the ball around. When the ball is stopped there isn’t any changes

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

Conclusion to Motion Lab Kerreon Wright 3rd Period Ms. Gislason The purpose of this Motion Lab was to find the acceleration of a steel marble going down a straight track six different times to figure out how an object’s mass affects acceleration. It doesn’t due to Newton’s second law of motion. There were six different accelerations for each trial and they are: 7.88 m/s squared‚ 6.78 m/s squared‚ 6.07 m/s squared‚ 5.57 m/s squared‚ 4.32 m/s squared‚ and 5.11 m/s squared. It’s possible

Kyle Brooks 11/13/12 Angry Birds Projectile Motion Lab How to Perfect Distances Of Birds using Launching Angles Purpose: The Purpose of this Lab is to discover which launch angles give the birds the longest and shortest time in flight. Hypothesis: I believe that the bird will launch the farthest at the 45 degree angle because that’s exactly half of 90 degrees which will give it the maximum height in comparison to length. I also think that the bird will launch the shortest at 0 degrees

Aim: To find the mass in grams (m) of a paperclip. Apparatus: Procedure: 1. Using a piece of string‚ the external circumference(C) of the small test tube was found and was then used to find A ‚ the cross sectional area of the small test tube A=C24π . 2. The beaker was placed under the test tube after it was clamped on the retort stand to collect excess water. The large test tube was filled with water. After which‚ the small test tube which had a fitted scale was placed inside to float
