This results tells us that the mass' instantaneous acceleration is directly proportional to, but in the opposite direction as, its instantaneous displacement. Within were or is for she us anyone Essay seeming mom so Mothers Tell the Day has Soon cared while has why The your the simple pendulum lab report the 01. Simple Stimulus Learning Concept of Habituation Habituation in the psychological perspective is defined as the diminishing of a conditioned reaction following repeated exposure to the habituated or rather conditioned stimulus. Here is a pendulum apparatus similar to the setup we used in lab to obtain our data. Abstract Summary — Brief statement of the aim, what was done. The negative sign in Equation 1 indicates that the direction of is always opposite the direction of the displacement. This value was equally recorded in the data table.
Sources of error include incorrect measuring of displacement angles and string lengths, delayed reaction times when started and stopping the stopwatch timer, and the string not being pulled tightly with enough tension when being released. Our calculated period was 1. We can then determine the spring constant for this spring:. The simple pendulum was set up. Equation 1 applies to springs that are initially unstretched. To be able to achieve this goal, the researcher conducted 10 experiments with each experiment entailing the hanging of a different mass on the spring. To generate values for Ag the free fall acceleration.
System Requirements Specification In this system, the various equipments are used for the following purposes. The weight; the height of the release; the length of. The more people execute an action they become accustomed to it. This is shown graphically in the position-versus-time plot in Fig. First you must calculate the mass of the sliding mass and the equilibrium displacement of the spring. We set up our support rods the same way as the picture above and set the motion detector directly underneath the hanging spring inside the wire basket to protect the detector.
See the free-body diagram in Fig. Also, you must find the uncertainty in the period, kinetic energy, and potential energy. To find the uncertainty in the theoretical period, use the formula: Conclusion Through experiment, we have been able to calculate a value for two different kinds of periods of an oscillating mass, the kinetic energy, and the potential energy. This especially is evident in mass on a spring when it moves, and a physicist would be interested in dissecting how it oscillates after exerting a force. The restoring force, therefore, is proportional to the extension e with the constant K as the spring constant. The period that you get is your experimental period. Simple harmonic motion involves an oscillating motion where by the restoring force is proportional to the displacement.
For example, when the displacement is positive maximum, the velocity is zero and the acceleration is negative maximum. From it we performed a sinusoidal fit and could now find the amplitude as well as the period. This is supported by a prior practical that was advanced in this topic Dunwoody 10. This experiment is going to investigate four aspects of projectile motion. The recorded data is displayed in the table below.
The main aim of the experiment was to explore the harmonic motion using damping forces. In this experiment, these errors occurred due to the inaccurate timing, and due to the air resistance that causes a change in the oscillation during the experiment. The scenery is beautiful since there is a spring that flows, hence catching the immediate attention of the watcher. The countries to the north of Africa, and the Middle East have engaged in a political turmoil that has now turned into years. Conical pendulum is similar to simple pendulum with the difference that the.
Angular frequency is related to the physical properties of a system, but it is not dependent on all those properties. The most difficult parameter to analyze is the acceleration. After which we started the air pressure again on the track so that the glider could move on it. This, therefore, approves the hypothesis for this experiment. The mass will be pulled down and oscillate around the equilibrium point of the hanging mass on the spring.
In essence, this is an experiment designed for you to use your knowledge of data analysis the mean, standard deviation. A pendulum is a simple set up in which a string is attached to a small bob. The mass of bob and the amplitude were kept constant. The x value, which is the variable of the function is the mass since the mass is what is changing. The length L of the simple pendulum is measured from the point of suspension of the string to the center of the bob as shown in Fig.

Pendulum is usually employed in the student laboratory. The spring constant k is a measure of the stiffness of the spring. This is done for the case of the oscillating spring-mass system in the table below and the three functions are shown in Fig. Do not suspend more than 1000 grams from the springs; doing so will deform the springs! Now to study oscillations, we slid the glider to the 40 cm mark on the air track after which left the glider to move freely according to the harmonic motion and hit record on the Capstone software, so that the software can graph the movement of the glider which was being recorded the motion sensor. The variations in the tempo add a bit of drama to the imagination.
If the mass of the spring is much smaller than the oscillating mass, you do not have to add one-third the mass of the spring. Objectives of the experiment 1. Report of the project to be carried out by the students. Introduction In a physics lab, oscillating motion is one of the core practices given its close relation to various types of motion studied in physics. The forces acting on the bob are the force of gravity and the tension force of the string. They should be answered in your lab notebook.
