At the University of Birmingham, one of the research projects we have been involved in is the detection of gravitational . Which would be turned back into kinetic energy as the mass moved to the opposite extreme. What is the uncertainty in the mass measurements? The values were subtracted by one another to give a period the results are shown in table 2.1. ( 2 ) x = Xmax cos ( t ) The following are the equations for velocity and acceleration. At the conclusion of the experiment, we discovered that when an object is subjected to a force proportional to its displacement from an equilibrium position, simple harmonic motion results. Since each lab group will turn in an electronic copy of the lab report,
Whilst simple harmonic motion is a simplification, it is still a very good approximation. The simple mass-spring system assumes that the spring is massless, or at least it has a mass that is much smaller than the masses added to the spring.
Solved Hello,I am needing a little help improving my lab - Chegg It is apparent that there is a clear relationship between an increased mass and the amount of force exerted, and consequently the amount of displacement experienced by the spring. Write the kinetic, potential and total energy of a baseball having a mass of 0.145kg held 10 meters. We repeat this experiment 2-3 time after that we stop recording and start to calculate the result. Our complete data is shown in Table 1.0 on the next page. 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.

V. Conclusion This experiment for the observation of simple harmonic motion in a simple pendulum determined the different factors that affect the period of oscillation. oscillating in a simple harmonic motion (SHM). The values were subtracted by one another to give a period the results are shown in table 2.1. The values of k that you solve for will be plugged into the formula: T = 2 (pi) (radical m/k). This way, the pendulum could be dropped from a near-perfect \(90^{\circ}\) rather than a rough estimate. 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 \(L\)).

It is important to make the additional note that initial energy that is initially given to the spring from the change is position, in the form of potential energy, would be perfecting conserved if friction played no role & the spring was considered perfectly elastic. determined? Equation 1 applies to springs that are initially unstretched. 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. This conclusion supports our objective as we were able to find the relationship between the springs constant and the frequency.

Simple Harmonic Motion Page 4 Sampere 0.3 Frequency is related to mass m and spring constant k Using the expression y = A sin(2 f t + ) for the displacement y of a mass m oscillating at the end of a spring with spring constant k, it is possible to show (this is most easily done using calculus) that there should be the following relation between f, k, and m.

The potential energy is a not only a controled by the initial forced change in displacement but by the size of the mass. We recorded these oscillations with data studio for about 10 seconds. 1. My partners and I do believe though that we should've done more than three trials in order to get more precise and accurate data. ,

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. 3 14.73 5 2.94 14.50 0.20 5 A good example of SHM is an object with mass m attached to a spring on a frictionless surface, as shown in Figure 15.2.2.

What is the uncertainty in the period measurements? All of our measured values were systematically lower than expected, as our measured periods were all systematically higher than the \(2.0\text{s}\) that we expected from our prediction. In Simple harmonic motion, the mean position is a stable equilibrium.
