S1210228Masashi Yoshida
How to Experiment
Experiment was a torsion balance made of a six-foot wooden rod suspended from a wire, with a 2-inch diamet-er 1.61-pound lead sphere attached to each end.
Two 12-inch 348-pound lead balls were located near the smaller balls, about 9 inches away.
Result
This experiment load to G This number was almost correct.

Universal Gravitation is...
Universal gravitation is one of the famous law of earth.
All things fall to the center of the earth.
Who did find Universal Gravitation?

?
There were some other ideas.
These are famous ideas.
Aristotle
Things try to back home.
Middle European people
All of things try to back old position. There were some problem about this.
Universal Gravity
From 1665, the law Newton find is said that this is correct.
We can use this law in universe.
supporter
Newton was supported by Hooke. To make sure this law.
Newton law
We call this law “Newton's law” .
We can calculate
We can calculate gravitational acceleration; acceleration of gravity and so on from Newton's law.
Some wrong understand
When Newton saw falling apple, Newton did not make sure Universal Gravity.
Conclusion
If Newton was not exit, This world was not exit.
Thank you for watching.
