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.
![**Understanding Angular Velocity in Tornadoes**
At its peak, a tornado is **55.0 m** in diameter and carries **505-km/h** winds. What is its angular velocity in revolutions per second?
[Input Box]
- rev/s
---
**Explanation for Educational Context:**
This example focuses on calculating the angular velocity of a tornado. Angular velocity is the rate at which an object rotates or revolves and is a critical concept in physics, particularly when analyzing circular motion.
**Key Components:**
- **Diameter of Tornado:** 55.0 meters
- **Wind Speed:** 505 km/h
**Goal:**
Find the angular velocity, expressed in revolutions per second (rev/s), using the given diameter and wind speed information.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff38196c1-b137-438d-8d5c-3c7913a77129%2Ff9724f02-74fa-4a92-9707-699ae59ca190%2F0o56lbr_processed.png&w=3840&q=75)
