Difference between weightless ness and free fall in Physics.

brother.... weightlessness is caused by an object being in free fall. But some differences can be seen
*free fall can experienced on earth
*weightlessness cannot be experienced on earth
*there is no change in the value of acceleration due to gravity (g)
*even though the object maybe at height but the gravity is not zero. It is only 11%less than real value
*when an object is thrown down on earth it falls
*when an object is thrown down in weightlessness condition it floats
*since, the object falls down sign convection is used to find out the direction of that object
*since, the object is still at its place sign convection cannot be used to find out the direction
this is it.
got any questions
make sure to ask.

Weightlessness is the complete or near complete absence of the sensation of weight.
It is also termed as zero G.
A free fall is an object where gravity is the only force acting upon it.
