ELI5: Explain Like I'm 5

Orders of magnitude (acceleration)

Orders of magnitude is like counting in huge steps. If you want to count from 1 to 100, it will take 100 steps. But if you want to count from 1 to 1,000,000, it will take you 1,000,000 steps.

Acceleration is how fast something is going faster and faster. Like when you ride a bike and you press the pedals harder and harder, the bike goes faster and faster. We measure acceleration in meters per second squared (m/s²).

Now we can use orders of magnitude to measure acceleration in big steps. Let's say we start with an acceleration of 1 meter per second squared (1 m/s²). This is like riding your bike calmly.

If we increase the acceleration by one order of magnitude, we multiply it by ten. So, 1 m/s² multiplied by 10 is 10 m/s². This is like riding your bike a little faster.

If we increase the acceleration by two orders of magnitude, we multiply it by ten twice. So, 1 m/s² multiplied by 10 and then multiplied by 10 again is 100 m/s². This is like riding your bike very fast.

We can keep doing this for as many orders of magnitude as we want. The important thing to remember is that each order of magnitude is a big step up in speed. It's like going from walking to running to sprinting in very big steps.

So, when scientists talk about orders of magnitude of acceleration, they are talking about how much faster something is going in big steps. It's a way to understand how fast something is accelerating without having to use very precise numbers all the time.
