1) Watch till 0:20
"Then the binding energy is the amount of energy that takes to completely separate them"
But the gravitational force between 2 masses can never be zero.
So the rocket would never be separated from Earth's gravitation which = infinite amount of energy required to separate them.
That means that the gravitational force of Earth has to be infinite.....this assumption should be wrong..
Am I right?
2) Watch from 1:20 to 1:40
If the nucleus has 60 nucleons then why is the radius only 2.5 nucleons?
3) I still don't understand....if energy required to break the bond = the binding energy then how will we get energy when we break the bond? Shouldn't we have to give the energy to break the bond?
Sorry if this is a little vague, if you don't understand what I am talking about then please watch the whole video.
