An object oscillates with an angular frequency ω = 2 rad/s. At t = 0, the object is at x0 = 5.5 cm. It is moving with velocity vx0 = 8 cm/s in the positive x-direction. The position of the object can be described through the equation x(t) = A cos(ωt + φ). What is the the phase constant φ of the oscillation in radians? (Caution: If you are using the trig functions in the palette below, be careful to adjust the setting between degrees and radians as needed.) Write an equation for the amplitude A of the oscillation in terms of x0 and φ. Use the phase shift as a system parameter. Calculate the value of the amplitude A of the oscillation in cm.
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.
