hung from an ideal spring (its length is equal to zero and no friction) and reaches equilibrium at position B when the spring has been stretched to the length l. The mass is then pulled to position C and released. The position C is of height h below the position B. The mass oscillates between positions A and C.
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.
A mass, m, is hung from an ideal spring (its length is equal to zero and no friction) and reaches equilibrium at position B when the spring has been stretched to the length l. The mass is then pulled to position C and released. The position C is of height h below the position B. The mass oscillates between positions A and C. [Neglect friction.] At which position, A, B, or C, is mass m located when the kinetic energy, gravitational potential energy, or elastic potential energy of the system is at a maximum? Explain the reason for each case.
