But this only works for small angles, about 5 or so. EssaySauce.com is a free resource for students, providing thousands of example essays to help them complete their college and university coursework. Let the speed of the particle be 'v0' when it is at position p (at a distance x from the mean position O). , 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. is the displacement of the body from its equilibrium position (at Download the full version above. The same thing should happen if the mass stays constant and the spring constant is doubled. oscillation of a mass-spring system. }V7 [v}KZ . @%?iYucFD9lUsB /c 5X ~.(S^lNC D2.lW/0%/{V^8?=} y2s7 ~P ;E0B[f! a) Conceptual/Theoretical Approach: 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. It will be interesting to understand what gives the mass the oscillating property.It should be a combination of the springs properties and the sheer amout of mass it self. By knowing the velocity in the second part, you can find kinetic energy and potential energy of the oscillating mass. In this experiment, we measured \(g=(7.65\pm 0.378)\text{m/s}^{2}\). If an applied force varies linearly with position, the force can be defined as Lab-Name-Rayhan Chowdhury. Figures 1a - 1c. Using a \(100\text{g}\) mass and \(1.0\text{m}\) ruler stick, the period of \(20\) oscillations was measured over \(5\) trials. Whilst simple harmonic motion is a simplification, it is still a very good approximation. 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. means the spring is soft.
