Simple harmonic motion (SHM) is a cool physics idea that you can see in your everyday life. SHM happens when things move back and forth in a regular way. Let’s look at some fun examples of SHM that you might see around you!
Think about a grandfather clock. It has a swinging pendulum. When the pendulum is pushed away from its resting spot, it swings back and forth. This swinging is a great example of SHM.
You can figure out how long it takes for the pendulum to swing back and forth using this formula:
In this formula:
You can easily see how the pendulum moves evenly and regularly.
Another example is when you attach a weight to a spring. If you pull the weight down and let go, it will move up and down repeatedly in SHM.
This motion is explained by Hooke's Law, which says that the force of the spring is based on how far you pull it:
Here:
Watching the weight bounce up and down perfectly shows SHM in action.
Have you ever plucked a guitar string? That is a fantastic example of SHM! When you pluck the string, it vibrates back and forth and makes music.
The sound you hear depends on how tight the string is, how long it is, and how thick it is. These different string qualities create different musical notes. The waves of sound you hear can be understood through ideas of frequency (how often something happens) and wavelength.
Think about a seesaw at the playground. When one kid sits down on one side, the other side goes up. This back-and-forth motion shows periodic movement.
Even though a seesaw doesn’t swing exactly like a pendulum, it still shows the basic idea of balance and movement around a center point.
Lastly, let’s talk about playground swings. When you push off the ground, you go up high then come back down. This is another example of SHM, as you swing back and forth in a regular way.
The angle you’re swinging at, the force of gravity, and how high you go all affect how you swing.
Finding examples of simple harmonic motion in real life helps us understand physics better. From the pendulum in a clock to the swings at a park, SHM is everywhere! Each of these examples shows important parts of SHM, like how things restore to their original position, how they move in a cycle, and how they create smooth patterns.
Next time you see something swaying or swinging, remember that it’s just nature showing off its physics!
