Hooke's Law and Simple Harmonic Motion - WebAssign and then released, it will oscillate about the equilibrium position. This conclusion supports our objective as we were able to find the relationship between the springs constant and the frequency. We are using the do-it-yourself , simple pendulum as the materials to determine the value of gravitational acceleration and, investigate the relationship between lengths of pendulum to the period of motion in simple, harmonic motion. The motion of a simple pendulum is one of the phenomena that can be used to approximate the simple harmonic motion. The rest of the first part requires you to add 20 grams to the hanging mass and then measuring how far the sliding mass has moved for the equilibrium position. Simple harmonic motion is a motion that repeats itself every time, and be constant movement vibration amplitude, fit the wheel with an offset from the body into balance and direction is always subject to the balance If an applied force varies linearly with position, the force can be defined as First, when you move away from the center of the balance is the strength of the system is again made to equilibrium, the force exerted is proportional with the shift by the system, and the example that weve had (installed by the spring mass) achieves two features. Fig 4. We also worry that we were not able to accurately measure the angle from which the pendulum was released, as we did not use a protractor. This was done by mapping the max position values of a series of 7 oscillations to their corresponding time value.

Then when the spring is charged with additional potential energy, by increasing the length to where can also be defined as the spring will exert whats called a restoring force which is defined as where is a spring constant. , This was proved experimentally with incredible accuracy. in the opposite direction, the resulting motion is known as simple harmonic /Filter /FlateDecode The spring constant is an indication of the spring's stiffness. The value of mass, and the the spring constant. A pendulum is a basic harmonic oscillator for tiny displacements. They also happen in musical instruments making very pure musical notes, and so they are called 'simple harmonic motion', or S.H.M. 692. General any system moves simple harmonic motion contains two attributes main. Simple Harmonic Motion and Damping Marie Johnson Cabrices Chamblee Charter High School . static and dynamic situations. A simple pendulum, is defined as an object with a small mass suspended from a light wire or thread, also known as, the pendulum bob. After we recorded the data, we did two more trials using two more different spring constants. Another variable we care about is gravity g, and then we are able to change the equation from T to g as follows: =2 (Equation 1) .

Additionally, a protractor could be taped to the top of the pendulum stand, with the ruler taped to the protractor. View PDF. Simple harmonic motion. PDF Simple Harmonic Motion and Damping - Gatech.edu analysis and conclusion. In a simple pendulum, moment of inertia is I = mr, so 2 T =. 27: Guidelines for lab related activities, Book: Introductory Physics - Building Models to Describe Our World (Martin et al. However, you may not have changed the spring constant, and if you didnt change it and measure what happened to the time T when you did, you cannot put that proportionality into your conclusion. . Lab Report 12: Simple Harmonic Motion, Mass on a Spring. experiment (MS Word format): Enter TA password to view the Lab Manual write up for this For a spring-mass system, such as a block attached to a spring, the spring force is responsible for the oscillation (see Figure 1). We will determine the spring constant, , for an individual spring using both Hooke's Law and the properties of an oscillating spring system.It is also possible to study the effects, if any, that amplitude has on the period of a body experiencing simple harmonic motion. We reviewed their content and use your feedback to keep the quality high. V= 45.10 / 3.11 = 14.5 oscillating body and the spring constant, Keeping the mass constant (either smaller or larger bob) and the amplitude (om <10') constant, determine the period for five different lengths (see Eq. PDF Guidelines for a Physics Lab Reports - Baylor University Conclusion: Effects the spring constant and the mass of the oscillator have on the characteristics of the motion of the mass. >> Question: Laboratory The simple pendulunm Purpose: investigate how the period of a simple pendulum depends on length, mass and amplitude of the swing Theory: The simple pendulum (a small, heavy object on a string) will execute a simple harmonic motion for small angles of oscillation. 5: A felt-tipped pen attached to the end of the beam The formula for this motion's governing law, known as Hooke's Law, is F = - kx, where F is the restoring force and the negative sign denotes the direction . difference was observed in the experiment. Holes open fully Holes open partially If the hanging mass is displaced from the equilibrium position and released, then simple harmonic motion (SHM) will occur. We found that the pendulum goes slower than simple pendulum theory at larger angles.

This has a relative difference of \(22\)% with the accepted value and our measured value is not consistent with the accepted value. be answered by your group and checked by your TA as you do the lab. force always acts to restore, or return, the body to the equilibrium Well occasionally send you promo and account related email. 3 0.20 5 21.30 17.73 0.18 19.05 13.57 0.33 We repeat this experiment 2-3 time after that we stop recording and start to calculate the result. Whilst simple harmonic motion is a simplification, it is still a very good approximation. We built the pendulum with a length \(L=1.0000\pm 0.0005\text{m}\) that was measured with a ruler with \(1\text{mm}\) graduations (thus a negligible uncertainty in \(L\)). is known as the spring force. = ln A0 / A1 determined? In the first part of this lab, you will determine the period, T, of the . . From your description, the square of the time T for one cycle of the motion should be directly proportional to both the mass value and the spring constant. If the block has not lost its capacity will continue to vibration, so they patrol movement is repeated every period of time and then well show it Simple harmonic motion. The period for one oscillation, based on our value of \(L\) and the accepted value for \(g\), is expected to be \(T=2.0\text{s}\). (See. 3: Dashpot (an oil-filled cylinder with a piston) for 14-16. For a small angle ( < 10) the period of a simple pendulum is given by 7-25,-(Eq. We first need to understand how to calculate the force of a spring before performing this lab. During this experiment, the effects that the size of an object had on air resistance were observed and determined. Don't use plagiarized sources. this force exists is with a common helical spring acting on a body. Now we start to open the speed control on and move the beam to start the graph on the chard, we turn the top plot on slightly to close the hole of dashpot. We thus expect to measure one oscillation with an uncertainty of \(0.025\text{s}\) (about \(1\)% relative uncertainty on the period).
