Ask a technical person what the acceleration of gravity (g) is and they will say

9.8 meters/sec^2 or 32 feet/sec^2

But how fast will I be going in 3 seconds?

Answer 66 mph. The not politically correct g is 22 mph/sec or 34 kmh/sec

I was trying to understand acceleration what does 32ft/sec^2 mean?

What is /sec^2? Oh! It means (32ft/sec)/sec

or 22mph/sec. At 1g each second you are going 22 mph faster.

I like how you put the acceleration of gravity into common and understandable units.

ReplyDeleteI hope you don't mind a little of my humor.

So, my Toyota Echo can out accelerate a Tesla. All I have to do is drive off a cliff! (And what will it do in second gear?)

32 feet/sec^2 sure sounds less painful!

So, that's 1320 MPH^2.
