In this part you will be looking at how Newton's Second Law relates to Simple Harmonic Motion and the ideal spring. The spring is pulling to the left on the cart and gravity is pulling down on the hanging mass. Because of these forces, the cart accelerates back and forth, and the mass accelerates up and down. This time, the force sensor is zeroed at the cart's equilibrium position. This means that the force sensor is not reading the full force of the spring. It is reading how much more or less than the spring force at the cart's equilibrium position.
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.
