Many sources can explain about first, second and third cosmic velocities, but the explanations contain difficult formulas and are not easy to understand.
For me, I can check it with powerful magnet and iron piece with flying nearby with him, falling to magnet,(lower than first speed), or may flying nearby few circles,(first speed), or fly away - this is illustrate of second speed. This is right? If this right, how about another way -》I just slowly grab iron piece in one hand and magnet to another - and slowly, certainly lower than first speed, separate them and move them away, piece from magneto. I don't use speed - I just use my muscle power, which excel power of magnet. Can we use only power, without big speed, for excel gravitation? And if yes, how I can calculate this power?
