6. A simple pendulum of length L = 100 cm is shown in Fig. P6.16. The angular dis- placement 0(t) in radians is given by BLAT (VE) 0(t) = 0.5 cos ovig 100 g = 9.8 m/s² re P6.16 A simple pendulum. gob (a) Find the amplitude, frequency, and period of oscillation of 0(t). (b) Find the time required for the simple pendulum to reach its first zero angu- lar displacement (i.e., 0(t) = 0). (c) Plot one complete cycle of 0(t), and indicate the amplitude and period on the graph. %3D
Simple harmonic motion
Simple harmonic motion is a type of periodic motion in which an object undergoes oscillatory motion. The restoring force exerted by the object exhibiting SHM is proportional to the displacement from the equilibrium position. The force is directed towards the mean position. We see many examples of SHM around us, common ones are the motion of a pendulum, spring and vibration of strings in musical instruments, and so on.
Simple Pendulum
A simple pendulum comprises a heavy mass (called bob) attached to one end of the weightless and flexible string.
Oscillation
In Physics, oscillation means a repetitive motion that happens in a variation with respect to time. There is usually a central value, where the object would be at rest. Additionally, there are two or more positions between which the repetitive motion takes place. In mathematics, oscillations can also be described as vibrations. The most common examples of oscillation that is seen in daily lives include the alternating current (AC) or the motion of a moving pendulum.
