A yo-yo with a mass of 0.4 kg is being spun in a vertical circle with constant tangential speed of 10 m/s. The length of the string it is attached to is 0.7 m long. (a)Draw a FBD of the yoyo at the bottom of its path and at the top of its path (Remember FBD should only show Force Vectors) Bottom TOP (b)Find the magnitude of the force of tension of the string at the bottom of the yo-yo’s path (c)Find the magnitude of the force of tension of the string at the top of the yo-yo’s path
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.
