When a body falls freely under gravity alone....it is said to be in a state of free fall
An astronuat in a spaceshuttle in earths orbit is constantly falling towards the earth with an acceleration of g, i.e the astronuat is under free fall. This acceleration acts the centripetal acceleration and hence the astronaut remains in orbit around the Earth..
Suppose u r in an elevator and the elevator begins to fall down with acceleration g. You will experience a pseudo acceleration in the upward direction then which will give rise to apparent weightlessness. The same thing happens to an astronaut in orbit around the Earth. There the pseudo acceleration becomes the centrifugal acceleration which makes the astronaut weighless.
As for the relation between weightlessness and free fall....a body under free fall experiences weighlessness.
Hope You liked the answer!! PLZ approve if u did....!
A body is said to be in free fall when it is only falling under the influence of gravity , so it has an accelaration of 9.81ms-2
an astronaut in a space shuttle experiences weightless , but since he doesnot fall under gravity in space , he doesn't have a freefall.
Weightlessness is the condition that exists for an object or person when they experience little or no acceleration.
Free fall is the condition that exists for an object or person when they experience accelaration due to gravity provided that it is not projected with any velocity i.e initial velocity = 0
Please approve

dear shivam ,
i m explaning u with the help of example ,
suppose there is a system of two masses , A , B ... ( MA >>>>>>>>MB )
A ................................. B (A & B are seperated by a finite distance)
if mass B is given certian energy so that it starts circulating around heavier mass &
its centripital force = gravitational force bw them then this condition is said to
be weightlessness .... (here centripital force exists to balance gravitational force)
now if no energy is given to mass B & it is placed near A then it experiences a net force
towards A & it is attracted towards A....this condition can be compared to
free fall... (here no centripital force exists to balance gravitational force)
now , instead of B assume it to be astranaut & A be the earth then
this explanation holds good ...
hi
if a body falls under the action of gravity that is with acceleration of 9.8m/s2 towards earth then it is said to be in free fall.
yes ,an astonaut in space vehicle orbiting around the earth experinces free fall that is centripetal accelaration is experienced.
as in a lift falling freely we expirience pseudo force ,, in a satellite pseudo force is nothing but centrifugal acceleration .thus he
feels weigthless.
plzzzz approve!!!!!!!!!!!!
