While at dinner, you notice a chandelier that looks like a simple pendulum swinging back and forth in the breeze once every T=6.3 seconds. a) calculate the frequency of oscillation in Hertz of the chandelier b) calculate the angular frequency "w" of the chandelier in radians/second c) determine the length "L" in meters of the chandelier d)at another restaurant you notice another chandelier that is completely identical to the first except this one swings back and forth 0.11 seconds slower, so the period is
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.
While at dinner, you notice a chandelier that looks like a simple pendulum swinging back and forth in the breeze once every T=6.3 seconds.
a) calculate the frequency of oscillation in Hertz of the chandelier
b) calculate the angular frequency "w" of the chandelier in radians/second
c) determine the length "L" in meters of the chandelier
d)at another restaurant you notice another chandelier that is completely identical to the first except this one swings back and forth 0.11 seconds slower, so the period is T+0.11 seconds. Determine the acceleration due to gravity in m/s^2 at the second restaurant
