Understanding mass and spring constant is important for making systems that bounce or swing well. Here’s how they affect how these systems work:

1. Mass ($m$): When something is heavier, it moves more slowly. For example, a heavy pendulum swings back and forth slower than a light one.

2. Spring Constant ($k$): A stronger spring makes things bounce quickly. For example, if a spring is tight, it squishes and stretches faster.

Together, we can use a formula for how fast things bounce in simple harmonic motion. It’s written like this: $\omega = \sqrt{\frac{k}{m}}$. This formula shows us that by adjusting mass and spring constant, we can control how systems like pendulums and shock absorbers behave.
