## Physics 123 Laboratory Manual

We will start with a simple exercise using the Excel spreadsheet to graph a set of points and to draw a best-fit line through these points. The lab notebook must be spiral bound, preferably with cross-hatched ruling. There are a variety of examples of projectiles. Was the object of the experiment met? Along with most of the experiments are suggested pre-lab activities that are meant to accompany each lab. The process starts with a hypothesis or educated guess on how something works.

Safety reminder Follow all directions for using the equipment. You can apply this knowledge to all kind of sports such as football, basketball, baseball, and more. . Computer Experiment Simulation Classical Mechanics. Graphs are either to be done on a computer or on quadrille-lined paper, for example, engineering paper. . Computer with Excel spreadsheet software 1 Lab balance 1 Vernier Caliper 1 Micrometer 1 Cylinders of four different types of metal 1 each Procedure 1.

If a piece of equipment is broken during an experiment, promptly notify your instructor or laboratory assistant who will remove the broken apparatus to a designated place and replace it with functioning equipment. The lab quizzes and lab reports will form the basis of your lab grade. When the points are selected, click the button icon on the minimized Chart Wizard box to maximize it, then repeat for the y values f. . When you arrive at the start of each class meeting, it is very important that you do not touch or turn on the laboratory equipment until it has been explained by the professor and permission has been granted to get started. Physicists try to apply a rigorous method of error analysis, and then compare results with respect to the inherent experimental errors.

The projections of the vector A upon the Cartesian axis are: i. Makeup Exam Possible make-up of missed labs. Human Arm To investigate the relationship between torque, moment of inertia, and angular acceleration for a human arm. E-1 Electrostatics: This lab first investigates types of charges and the forces between them by experimenting with everyday objects. If appropriate, should also include a comparison of various experimental errors. Equipment: Apparatus used to perform the experiment. There will be no exceptions to this rule.

The students will then hand in written or typed reports, either individually or as a group. Each student, student assistant, and instructor that uses the lab is required to receive a safety briefing before beginning laboratory exercises. This lab focuses on the one dimensional case where each quantity can be considered as a scalar. Save your file as group-x-phys2111-P0y. For the activities that include a computer assisted component, the computerized version is presented along with the traditional version, giving the class a choice of whether or not to use the computer interface equipment for that particular lab. .

While the experiments done in Physics I classical mechanics are generally safe, it is always important to be cautious when using equipment, especially if you are unfamiliar with the equipment. This means that the error cannot be corrected by the experimenter after the data has been collected. Gravity is the downward force upon a projectile which influences its vertical motion and causes the parabolic trajectory which is characteristic of projectiles. In polar coordinates, A is the magnitude of the vector its length and θA is the angle to the vector as measured counter-clockwise from the positive x-axis of a Cartesian coordinate system. Error propagation It is up to your instructor whether error analysis will be included in your lab assignments.

. . In textbook problems, the initial velocity of an object is typically given, and the subsequent motion is described with equations of motion. Today we will examine the rules of algebraic vector addition. Projectile motion is simply the motion of an object in a plane two dimensions under the influence of gravity. In some cases, a blank template will be handed out for the each group to fill in; in others, the group may be asked to write their report, following the below format, on a computer or by hand on paper.

Density is defined as the mass of a substance divided by its volume. It is required that safety glasses be worn when doing all the procedures. Standing Transverse Waves Using Vibrating Strings. This is the Laboratory Manual for the second course in the General Physics sequence. If only one measurement was taken, use ½ the smallest scale division of the measuring device. The temperature at which this occurs is absolute zero.

It also explains some of the concepts required to be understood in order to successfully complete this course and provides examples from everyday life illustrating the concepts. No theory is held to be tenable unless the results it predicts are in accord with experimental results. . Then you use an electroscope to understand how electrons move in conductors, and how other nearby charged objects influences this charge motion.
