The standard deviation from length, diameter, and mass were 0, .0819, and .041 respectively. The measurement for length was probably the least precise measurement taken. We used a meter stick, but kept getting the same measurement, probably due to the meter stick not being very precise.

...Abstract: In performing the Simple Harmonic Motion Lab, our goal was to determine the period of motion for objects performing simple harmonic motion. We did five trials of measuring the time it took a pendulum to make 30 complete oscillations. We divided that time by 30 to get the period and then took the average of all 5 trials, getting an average period of 1.88 seconds. To compare our results, and see if they were correct, we used the given equation for the period of motion that includes the length of the pendulum to calculate the period for the same pendulum, resulting in 1.87 seconds, which agreed with our earlier results. This shows that period of oscillations can be determined by length and gravitational acceleration, and doesn’t depend on mass.             In our other activity, we measured the period of an oscillating mass connected to a spring. We had a hanging spring, and hung mass to the bottom of it, each time measuring the change in length of the spring from the time before. To find the spring constant, we used the masses added to calculate each of their elastic forces, by multiplying each by gravitational acceleration, then plotting them with their corresponding spring deformation, and the slope of that graph was the spring constant, k, which was 8.22 N/m. Using this value, we calculated the period of motion for the mass of 0.1 kg using a different given equation than the one before, obtaining a period of 0.69 seconds. To verify our results, we used the......

...Lab Assignment 4: Types of Force Instructor’s Overview In many physics problems involving Newton’s laws of motion, you’ll see statements like, “assume a frictionless surface” or “neglecting air resistance…” In this lab we will be exploring both friction and air resistance, two resistive forces that are critical in the design of real-world products and systems. Understanding the effects of these types of forces is essential in the design of such things as aircraft, automobiles, braking systems, and countless other objects. This activity is based on Lab 4 of the eScience Lab kit. Although you should read all of the content in Lab 4, we will be performing a targeted subset of the eScience experiments. Our lab consists of two main components. These components are described in detail in the eScience manual. Here is a quick overview: * In the first part of the lab, you will measure the force it takes to pull objects of different mass. This experiment focuses on the effects of frictional forces. (eScience Experiment 1) * In the second part of the lab, you will investigate the effects of air resistance by performing controlled drops of coffee filters. Notes: * Please follow the instructions in this document for the air resistance experiment. * Record all of your data in the tables that are provided in this document. Take detailed notes as you perform the experiment and fill out the sections below. This document serves as your lab report. ......

...Acceleration of a Cart Purpose: The purpose of this lab is to find the relationship between acceleration, force and mass using a cart system. Equipment: • Motion detector • Pasco GLX • Cart • String • Pulley • Hanging Weights & Metal Cubes • Ramp • Ruler Procedure: Experiment 1: 1. Weigh and record the mass of the cart (this will be kept constant for all trials) then the mass of the cart with all the hanging weights on top of it. 2. Take 1 hanging weight off the cart and attach it to the end of the string on the cart with the other hanging weights still on top. 3. Place the cart on the ramp in front of the motion detector. 4. Set the GLX using the correct units for the y and x axis for graphing. Then measure 20cm away from the motion detector, place the cart there and start the GLX and release the cart from 20cm at the same time. Stop the GLX and the cart few centimeters before the cart reaches to the end of the ramp for precise data. 5. Repeat steps 2, 3 and 4 by adding 1 hanging weight to the string of the cart with the previous hanging weight already on the string until all hanging weights are used and not left on top of the cart. Then record data. Experiment 2: 1. Weigh the hanging weight and record the mass (this will be left constant for all trials). 2.

...Monday 4:30pm – 7:15pm Course Name: Physics 246 Lab Partner’s Name: Jennifer Darlington, Hyon Hodge Date: 11/12/2012 Instructor: Dr Vermuru Word Count: 1650 Aim: The aim of this experiment is to examine a scaled up model of the human eye to understand the image formed in the eye, the optics of accommodation, nearsightedness, and farsightedness. Introduction: The basic structure of the human eye consists of cornea, natural crystalline lens and retina, as shown in Figure 1, in which the lens of the eye does little of the bending of the light rays, most of the refraction is done at the front surface of the cornea and retina plays the role of the film in a camera. Figure 1: Diagram of a human eye Accommodation is the focusing adjustment in which the muscles in the eye change the shape of the crystalline lens to change its focal length. Figure 2: Accommodation by a normal eye a) Lens relaxed, focused at infinity b) Lens thickened, focused on a nearby object Nearsightedness refers to an eye that can focus only on nearby objects. Because the far point is not infinity but some shorter distance, distant objects are not seen clearly. This defect is usually caused by an eyeball that is too long and images of distance objects are focused in front of the retina. In order to correct this defect, a diverging lens should be used as it causes parallel rays to diverge which allowing the rays to be focused at the retina. Figure 3: a) Nearsighted eye b)......

Physics 100b Buoyancy Lab

...1. Theory: In this lab, we used the equation (Fb = pgV) to figure out the buoyancy of three different objects. We then used a force sensor to give us an actual reading of the force, or weight, of the object and we found the buoyant force by using the equation (Fb = Wout – Win). We then used our theoretical value for buoyancy and our measured value to find the percent error. Lastly, we used a tuna can as a boat and found the volume of the tuna can. This volume is the supposed capacity that the can will hold before sinking in the water. 2. Procedure: The first thing we did was measure the volume of the three objects. For the aluminum cylinder, we measured the radius and length (V=pi R^2 h) to find a volume of 2.29X10-5m^3. We measured the radius of a brass sphere (V=4/3 pi R^3) to find a volume of 2.91X10-5m^3. And lastly, we measured the length, width, and height of an aluminum block (V=LWh) to find a volume of 4.03X10-5m^3. Next, we used the buoyancy equation, plugging in the density of water and the volume of our object, to find the predicted buoyant force. Next, we used a force sensor and weighed our three objects before they were placed in water, and while they were submersed and solved for the actual buoyant force. We compared these two numbers and solved the percent difference. Finally, we measured the radius and height of the tuna can to give us a volume of 211.86cm^3. This means that the tuna can should be able to hold just about 211.86g of weight......

Chapter 2 Theory Motion: In physics, motion is a change in position of an object with respect to time. Motion is typically described in terms of velocity, acceleration, displacement, and time. Motion is observed by attaching a frame of reference to a body and measuring its change in position relative to another reference frame. A body which does not move is said to be at rest, motionless, immobile, stationary, or to have constant (time-invariant) position. An object's motion cannot change unless it is acted upon by a force, as described by Newton's first law. An object's momentum is directly related to the object's mass and velocity, and the total momentum of all objects......
