AI Thread Summary
The discussion centers on the effect of Earth's rotation on gravity, specifically how centrifugal force alters the perceived force of gravity. Without Earth's rotation, gravity would be stronger due to the absence of this outward force. Participants reference calculations involving angular velocity and centrifugal force to illustrate their points. The conversation emphasizes the importance of understanding these forces in relation to the current gravitational pull experienced on Earth. Overall, the impact of Earth's rotation is significant in determining the effective force of gravity.

What would the force of gravity really be, without the Earth's rotation providing centrifugal force?

(In terms of current g-force)

come on, you can work this out for yourself …

ω = 2π/60*60*24,

and the centrifugal force is mω2r towards the Earth's axis (ie not vertical) :wink:​
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
