    No its not a specific question. I am just confused why we always take r as the radius of Earth in the formula of Escape speed?

    Physics: Post your doubts here!

    When we calculate Escape Speed, we use the formula square root[2GM/R]. Here why do we assume the radius,r, as the radius of Earth,R? Escape speed is the speed with which a body moves from gravitational field to infinity. What if its initial position in the gravitational field from where it...

    I think they have been experiments to their captors so they were named like experiments. Like we say this is experiment Alpha, beeta etc. But Thomas and Teresa were amongthe captors initially so their names are normal.
