2048L/Lab 2/Lab Manual 2 c.pdf 1 Lab Manual Irina Golub July 30, 2017 2 PART ONE: Photographic Analysis of a Falling Object INTRODUCTION With the great advances that have been made in digital imaging and analysis, experimental data is often in the form of photographic images. In this experiment, you will make displacement measurements of a tennis ball dropped from a height using photographic data and your computer’s mouse positioning system. From two displacement measurements and the time between these measurements and one of the five kinematic equations that describe one- dimensional motion, the acceleration due to gravity on earth, “g”, will be estimated. Since you know what the correct answer should be (9.8 m/s2) you will be able to calculate the percent error of your estimate. Neglecting air resistance, a falling object increases its speed 9.8 meters per second every second that it falls on earth. This is “g”, the acceleration due to gravity. Below you will see snapshots taken of a falling tennis ball at equal intervals of time (0.1 second between frames). You can see that the displacement of the tennis ball increases during each successive time interval. This is due to the tennis ball speeding up in each time interval, i.e., the tennis ball is accelerating. Read University Physics Volume 1 Chapter # 3: MOTION ALONG A STRAIGHT LINE EQUIPMENT A PC running MS Internet Explorer web browser. (Other web browsers may not work for this experiment.) OVERVIEW The photographic data file shows one composite photo made by splicing six separate images of a tennis ball dropped straight down. Each of the six separate images was taken 0.1 second apart. Just below the photo in the photographic data file you will see boxes labelled X and Y with numbers that change when you move the mouse over the photo. These numbers are mouse coordinates in what we will call “mouse units.” You will record the Y-position of the ball in the first and last image (i.e., ball image #1 and ball image #6) (the X-direction is not needed as the object was falling straight down). Since the numbers you record will be in mouse units and not meters, only the difference between these two measurements will be important. You will be able to convert this difference from mouse units into meters because there are two meter sticks joined together vertically in each photo as a reference. [If you are unable to see the mouse coordinates in your browser and are unable to get to a BCC lab computer you can measure ruler coordinates instead of mouse coordinates using a plastic ruler held near (but not touching!) the computer display. Substitute the phrase ”ruler coordinates” for ”mouse coordinates” in the procedure and questions. Take your measurements in millimeters. This will not be as accurate as using mouse coordinates which have a higher resolutio.

115L Lab Two Using Graphs to Recognize Mathematical Relations: Displacement, Velocity and Acceleration 1 Introduction Many of the things that are studied using physics are processes that change over time. A system being studied will have some initial configuration at the beginning of the observation. As time goes on, the system will evolve into a new configuration. One of the most common practices in scientific study is to keep detailed records of a systems configuration through a period of time. This allows the observer to look back at the systems evolution as a function of time. Often, the function will follow a consistent mathematical relation that leads to the equations used to model physical processes and predict the behavior of systems. Today you will look at a simple system, a cart moving in one dimension along a track. You will look at separate functions for the cart’s position along the track, the rate of change of that position (the velocity), and the rate of change of the velocity or amount that the cart is speeding up or slowing down (the acceleration). Plots of the functions, all functions of time, reveal the simple mathematical relations that each follows. Features of the plots also clearly show the connections between the three functions: position, velocity and acceleration. Theses connections are what led Newton and Liebniz to invent calculus. Study- ing the connections between the graphs of these functions is an illuminating illustration of the basic principles of calculus, and how they appear in the physical world. 2 Making a Graph of Position as a Function of Time You have a track set up at a low angle, and a low friction cart to roll down the track. At the top of the track there is a motion detector. The motion detector sends an ultrasonic pulse, and then detects the reflection. The time delay between the sent and received pulse allows the detector to calculate the distance to the object that the pulse reflected from. A series of these measurements over time allows the motion of an object to be tracked. 1 • Make sure the detector’s switch is set on the narrow-beam setting. • Make sure the detector is aimed parallel to the track. • Open the DataStudio file PS115L.Position1. • Hold the cart about 20 cm from the detector. Make a note of the starting position: • Click “start” on the DataStudio interface and release the cart. Try to time your release of the cart as close as possible to the start of the data collection. Click stop just as the cart reaches the bottom of the ramp. Catch the cart as it reaches the bottom!! • Identify the initial position of the cart. The data table may have several readings near the beginning of the data set with values that do not vary, or vary only slightly. Use the average of these values as the initial position of the cart before the release. • Identify the last relevant data point. If you timed your “stop” correctly, you will be able to use the data all the way to the end..

Final Report

PHYS 221 Lab 1 - Acceleration Due to Gravity Please work in groups of three. Please submit one lab report per person via Canvas. In this laboratory we will measure the acceleration due to gravity by studying the motion of a cart accelerating down an inclined plane. Background Suppose we start with a level track and then tip it, as shown in Figure 1 below. Let L be the distance between two fixed points on a ramp, selected to be as far apart as possible, on the track. Let h be the difference in the vertical height above the table of these two points. Figure 1 - Schematic of a cart on an inclined plane. The magnitude of the acceleration of the cart down the ramp can be considered a component of the gravitational acceleration: a = g sinθ Then we have an incline of angle  given by Equation 1: . (1) The acceleration of gravity, g, acts vertically downward, so the component of parallel to the incline – which is the acceleration of our cart – is given by Equation 2: (2) We see in Equation 2 that a graph of acceleration a as a function of sinθ should be linear with slope g. We will take data to plot such a graph and from its slope determine the value of g. Setup Gather the following materials: · 2 m ramp · Meter stick · Lab Stand · Ramp clamp · Plastic Box with ULI, AC Adapter, and USB Cable · Motion Sensor · Magnetic Bumper 1. Connect the ULI to the computer via the USB cable and connect the AC adapter. Open Logger Pro 3.8.7. 2. Attach the ramp clamp to the lab stand and attach one end of the ramp. 3. Elevate one end of the track slightly using the vertical rod. Choose a value of h so that the angle of inclination stays less than about 8 degrees. (Use Equation 1 to verify). · You can choose any two points along the track to serve as your L, but they must be the same two points for all your runs! · Measure h by measuring the difference in the two heights of your two points. 4. Connect a motion sensor to the ULI and mount it on the elevated end of the track. The low end of the track should have a magnetic bumper installed on it (magnets face upward along the track). Procedure 1. Choose at least five values of height h, to vary  over the range 1-8 degrees. 2. Record each value of h chosen, and then obtain a graph of velocity versus time for that value. 3. You have two options for collecting velocity data from the cart: · Release from the elevated end of the track and let it accelerate to the lower end. · Push the cart from the lower end of the track up the incline. Record data during its entire motion back to its starting point. This will take slightly more finesse, but the data will be better. The motion sensor will not record accurate data for a cart closer than 40 cm (the limit of its near range). Do not let the cart collide with the end of the track! 4. Determine the acceleration for the cart by using the Linear Fit tool and highlighting the appropriate region of the velocity graph. Record the .
