I find a spring that is labeled "80 N/m", but it is actually 3.5 inches long. I fasten a beam (horizontal rod) 789 mm above the table-top, and hang the spring from it. Where is the spring's bottom end? (presume the spring does not stretch due to its own weight; 1 inch is 25.4 mm) O 786 mm above the table 307 mm above the table 89 mm above the table 709 mm above the table 878 mm above the table 780 mm above the table 789 mm above the table 70 mm above the table 777 mm above the table 700 mm above the table O touching the table-top
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.
