A slider is attached to an ideal spring and oscillates on a frictionless horizontal track. At a given instant it passes through the point where its acceleration is zero. which of the following statements is correct for that instant? 1. The potential energy is zero. II. The kinetic energy is zero. III. Mechanical energy is zero. IV. The force exerted by the spring is zero. a) I AND IV b) II AND IV c) II AND II d) IAND II
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.
