Is there friction present outside the earth?That is in space?
We saw in Newton's laws of motion that if we apply an external unbalanced force on a ball,it will move and also will come to a stop because of gravitational pull and also frictional force. If we do the same thing in space,will the ball come to a stop?
Because,in space there is no frictional force and no gravitational pull,so will it come to stop?
Since in space there is no friction, so if a body is given a force once then does it stop or does it continues to move or do work without stopping forever (until something stops it )?
If there is always a small spacing between two bodies in contact with each other how is friction generated.?
