Question

what are(1) free fall,(2) acceleration due to gravity,(3) escape velocity,(4) centripetal force?

Answer 1

Hello,

FREE FALL:- ] Free fall is the motion of an object in which it is affected only by the influence of gravity. 



ACCELARATION DUE TO GRAVITY:- The accleration which is gained by an object because of the gravitaional force
It is called accelaration due to gravity.

ESCAPE VELOCITY:- ] The lowest velocity which a body must have in order to escape the gravitational Attraction due to.


CENTRIPLE:- Force applied on an object moving in a circular path which attracte to the objects towards that mean centriple.



that's all
