LEARNING OBJECTIVE: 7. 3 Describe the displacement, velocity, and acceleration of an object exhibiting SHM. As described in previous section the force and acceleration of a body of mass m performing SHM can be related as : $F = m a = – kx$, hence $a = – \frac{k}{m} x = – 4 \pi^2f^2 x $ This means we can find the frequency of the vibration from the force equation as...
Vibrations and Simple Harmonic Motion
LEARNING OBJECTIVE : 7.1 Describe Simple harmonic motion 7.2 Describe the frequency and period of an object exhibiting SHM. Consider the following motions: An object pushed on a frictionless surface: The object will start moving as the work done by the person pushing it converts into the kinetic energy of the object. The object will continue to move in one direction continuously unless disturbed...
