ELI5: Explain Like I'm 5

Axis angle

Okay kiddo, let me tell you about axis angle. Have you ever played with a toy car and imagined it turning around on a certain point? That point is called an axis.

Now imagine a toy soldier standing on the ground and he wants to turn around on his own axis without moving his feet. He can only do this by turning his body around that imaginary axis point.

That imaginary point and direction the object is turning are the two important things that make up the axis angle. The axis is the point where the object is turning, and the angle is the amount of turning that is happening.

This concept is used a lot in math and engineering to describe how objects rotate in space. It helps us understand how things move and change direction.

So, just like how you can imagine your toy car or soldier turning around an axis, scientists and engineers use axis angle to help imagine and explain how things move and turn in real life.
