Set the controls as follows. • Xo = -4 cm • k = 50 N/m • m = 5 kg If you wanted to adjust the settings but keep the period the same as in the above what would you do? (Hint: Think about the dependency of period on the initial displacement, spring constant, and mass. S Odouble the value of x, and halve the value of k halve the value of x and halve the value of k Odouble the value of k and double the value of m O double the value of k and halve the value of m halve the value of x, and double the value of m halve the value of x and halve the value of m Part IV Set the controls as follows. • Xo = 8 cm k= 100 N/m • m = 7 kg Now hit start and observe the motion of the block and the plots on the graph for acceleration, kinetic energy, and potential energy. Which of the following statements accurately describes your observation. (Select all that apply.)
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.
