1. A student is given a block and a spring. He is told that the block has a mass of 0.500 kg and that the spring constant is 60.0 N/m. He calculates the theoretical period of oscillation will be 0.574 s. He then attaches the block to the spring and times the period using 20 oscillations. He discovers that the actual period of oscillation is 0.450 s. Which of the following statements best explains the discrepancy between the theoretical and the actual period of oscillation? A) Air resistance was ignored in the theoretical calculation. B) The spring's mass was ignored in the theoretical calculation. C) The spring constant was less than 60.0 N/m. D) The block's mass was less than 0.500 kg.
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.
