Recording Results the mass will be at a distance xfrom the equilibrium position. Lab 2 Jan 28-Feb 3. It is an example of simple harmonic motion. You need to hang enough mass to the end of the spring to get a measurable stretch, but too much force will permanently damage the spring. To demonstrate weightlessness in free fall. mass of box – Can be read directly from the scale. A set of 10 experiments is used in the “standard list” of experiments, but the individual instructor may switch one or two of them for another on the list. Conducting the Experiment Mass-Spring Conducting the mass-spring test was done by first attaching a weight on to the end of a spring and letting it settle to an equilibrium state (in which the mass is not in an SHM). Make sure that the detector is as close to vertical as possible. Method and Materials: Density is the amount of mass per unit volume of a substance: dV dm!= (8-1) For substances with constant density (has the same amount of mass in every unity volume throughout the object) the density is V M!= (8-2) M is the total mass of the object and V is the total volume. Mass versus Weight Lab Report. In this part of the lab, you will determine the angular frequency of a 170-g mass (50 g for the stand, 20 g for the CD, and a 100 g mass) oscillating on a long (not very stiff) spring. For example the group at lab table #5 working on the Ideal Gas Law experiment would rename their template file as "5 Gas Law.doc". acceleration due to gravity.

In your lab report describe how you determined the potential, kinetic and total energies of the system, the equilibrium position of the mass and spring constant of the spring. The centripetal force in this experiment is created by he spring, as shown to the right, and is thus given by: = F c (4 2mr) T2 The force created by a spring is proportional to how far past equilibrium it is stretched, in this case represented by r as shown. If pH levels range from 0 to 6, then calcium carbonate shell has a higher chance of dissolving. Since this fact has already been established, the hypothesis of this lab experiment will assume the same thing. This rectangular bar contains holes equidistant from each other and two extra with equal masses of 1.85kg, are made to peg through these holes. Record the initial mass in the Lab Report section, Table 1. 10A-Lab Report: Simple Harmonic Motion- Mass on a Spring Name: Data Sketch your graph of Position versus Time for Run #1 Data Table So t tem Run Run #2 Suspended Mass 7589 776 Mass of the spring Spring Constant Period (average) 0,7gS s l 0.9399 s] Value for k found by doing Hooke's Law Calculation The spring you are using in this experiment is heavy enough that its mass cannot be neglected. ), the lab group should design an experimental protocol to determine the following material properties of the sample: density, modulus of elasticity, and damping ratio. Hooke’s Law states that within the limit of elasticity, stress applied is directly proportional to the strain produced. Lab Report Format: Your lab report for this experiment should contain: 1. As you turn up the current in the Helmholtz coils, the electrons will curve to the left. (No cookbook here!) Record the apparent mass. The tools needed for this lab are as followed: a spring apparatus, a mirror length scale, various amounts of masses, a mass hanger, and a spring. In the present experiment a beam of electrons is accelerated through a known potential, so the velocity of the electrons is known. With the help of the digital scope, adjust the DFT offset so the signal is symmetric about 0V. Attach a 50 g weight hook with a 50 g slot mass on it to the spring. Purpose statement (why and how): In order to test torque experimentally, mainly whether the definition of torque holds true under differing angles and distance from point of rotation, we performed an experiment using a meter stick, a spring force meter, a mass, a protractor, a rubber band, and a fulcrum/balance point. Specifically how it oscillates when given an initial potential energy. In Method 2 the mass of the glider was the independent variable. Be sure to clamp the ring stand to the lab table, or weight it with several books so that the mass does not pull it off the table. 2.There are also masses ranging from 100 g to 500 g in the set. Imagine a spring that is hanging vertically from a support. Introduction and safety; check-in; citing information for the laboratory. The purpose of the pre-lab is to get students thinking ahead to the subsequent experiment, so as to arrive better prepared on the day of the experiment. Our constants were the amplitude, the type of spring we used (in other words the spring constant), the number of cycles we wanted to measure out.
