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.
an object of mass m1 = 9,0 kg is in equilibrium while it is connected to a line spring of constant k = 100 N / m and that it is fixed to a wall in the way shown in Figure P12.38a. A second object, of mass m2 = 7.00 k, is slowly pushed against m1, compressing the spring to a distance A = 0.200 m (figure p12.38b). The system is then released and both objects move to the right on a non-friction surface. to. when m1 reaches the equilibrium position, m2 loses contact with m1 (figure p12.38c) and moves to the right with a speed v. Determine the value v. b. How far apart are the objects at the moment the spring reaches its maximum elongation for the first time (D in figure p12.38d)? (hint: first, determine the period of oscillation and the amplitude of the spring system -m1 after m2 loses contact with m1
