a block of mass 1 kg rests on a frictionless floor. A spring constant of 180 N/m attaches the block to a wall, the spring is parallel to the floor. Suppose that the mass is oscillating on the spring, and at some time, the mass passess through the equilibrium position with a speed of 1 m/s. A) What will the amplitude of the oscillation of the mass? B) How far from the equilibrium position will the mass be at a time 2s later?
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.
