Concept explainers

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 weighing 4 kg, one end of which is connected to the other end of a spring connected to the ceiling, makes an oscillating movement in a frictional environment. It is known that the friction force is proportional to the speed of the object and its proportionality coefficient is 5 Ns/m and the spring constant is 0.2 N/m. At t = 0, the object starts to move after being raised 2 m upwards from the equilibrium position, and it is known that it passes 5 m below the equilibrium position at t = 10 s. Write the differential equation that describes the motion of the object and then find the equation that relates the position of the object to time.

People who ride motorcycles and bicycles learn to look out for bumps in the road and especially for washboarding, a condition in which many equally spaced ridges are worn into the road. What is so bad about washboarding? A motorcycle has several springs and shock absorbers in its suspension, but you can model it as a single spring supporting a block. You can estimate the force constant by thinking about how far the spring compresses when a heavy rider sits on the seat. A motorcyclist traveling at highway speed must be particularly careful of washboard bumps that are a certain distance apart. What is the order of magnitude of their separation distance?
A 2 kg mass is hung from a spring with spring constant 10 N/m. The overall shape and size of the object gives a drag coefficient of 11 Ns/m. The object is allowed to hang at rest on the spring, and is then dragged downward 0.8 m and pushed upward with a velocity of 1.5 m/s as it is released. Write an initial value problem describing the motion of this mass as a function of time. You do NOT need to solve this initial value problem, just write it completely. Is this physical system undamped, underdamped, critically damped, or overdamped? Explain your reasoning. Pick one of the parameters in this problem and change it to make the physical system critically damped. Your answer should include the part of the problem statement that you are changing, what you are changing it to, and how you know this makes the physical system critically damped.
