Question

1) WHEN DOES A FORCE BEETWEEN TWO OBJECT ARISE ?
2)how does one find the resultant of forces that are acting
either in the same or in the opposite direction on an object?
3)What do you mean by ' state of motion ' of an object?
4)two forces f1 and f2 act on an object towards the left and two
forces f3 and f4 act towards the right determine the magnitude of
the resultant force on the object can you tell on what factors will
the direction of resultant force depend?

(1) Force generally arises due to contact of the source
(producing force) with as object as a push or a pull
(3) State of motion refers to the condition/physical
configuration of a body when it is moving with a certain
velocity
(4) net force = (f1+f2) - (f3 + f4)
