So, straight to topic, my title describes what I want to know. I tried searching online, but I did not come upon anything that explains how Newton came to find the value 9.8m/s^2, or even whether he did.

Also, if you happen to know, how did Newton come up with his law of universal gravitation? [G=m1*m2/r^2]

All replies will be appreciated. Thank you!
