When 1/5 Kg (200g) mass is applied vertically to an elastic spring, the spring is stretched 10 cm from its normal position. A spring is stretched by attaching 200g (0.2 kg) to distance of 10cm. It was pulled and allowed to oscillate +/-10 cm up and down. What will be maximum velocity of the spring in m/s, if the spring is oscillating between +/- 10 cm up and down? (Assuming gravity = 10.0 m/s2)
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.
