If the net force acting on an object is zero,then will the body remain necessarily in rest position
Answers
Answer
NO
Explanation
In real life there is no situation of net force=0 which is possible( except in the books ).
When the net force on a body is zero , it implies that the body will/cannot be accelerated. This follows from Newton’s second law of motion.
F= m * a;
where ‘F’ denotes force , ‘m’ denotes mass and ‘a’ denoted the acceleration.
When net force is zero , F=0 . So m * a should be zero too.
But your mass cannot be zero !!!. SO , acceleration should be zero.
Acceleration is what changes your speed( precisely the rate of change of velocity) . When there is no acceleration , then the body continues to move with whatever speed it had before.
This speed can be any value including zero. At zero speed the body remains at rest , ie,, wont move.
SO it does not necessarily mean that the object should be at rest.
No, force is applied both on a moving and still object. Thus,it will not necessarily stay at rest
