what is the physical indipendence of force, define it

Answer 1

hey mate here is ur answer :-) :-)
____________________________________


Physical independence of force means first law of newton.....


force (F) acted by a body of mass (M) , there is an equal and opposite force (F) experienced by mass (M).

firstly , we will understand what is force ?

Answer :- A push or pull applied on a object that change the state of the object is called force.

example :- when we push a moving ball, it gradually slows down and comes to rest due to force of friction. (frictional force).

now , what is physical independence of force ?

Answer :- Newton's first law states that “if a body is at rest ,it remains in rest and if it is in uniform motion then it will continue its uniform motion untill an external force is applied on it”
So according to Newton's first law - “Force is an external factor which can change the state of rest or state of uniform motion of an object”.
