Weightlessness of a object

 

Let's first see what weight loss is all about ?
It has been said that if an object does not feel the force, it will be called weightlessness.
Sir Issac Newton said in his second formula about the ball, It is force = measure * acceleration.


Again we know about weight = measure * acceleration
 So related to force and weight- 



 


Now the things is gravitational acceleration always acts on all objects then how did weightlessness happen or whether the the event is actually possible ?? 

Where the value of gravitational acceleration is hero or the velocity of the object particle is greater than the gravitational acceleration then the weightlessness of the object will be.


Example : 


·      In the center of the earth t Here, if the radius of the earth is zero, then the value of gravitational acceleration.

· In space t Weightlessness is observed in space as there is no effect of gravitational acceleration

·   If the speed of the object is greater than the gravitational acceleration :-  If the velocity of an object is greater than 9.8 meters per second square and if that object were to run towards the earth, it would feel weightlessness. Such incidents may be observed in elevators.
