For example,if a body is at rest, if we apply a force towards front then it moves front and changes its state of motion  this all depends of newton's 1st law of motion.

Yes, i agree with your piont.
for example,
1)a person sitting in the bus falls front in the bus suddenly stops.This is due to the inertia of motion
2)a person sitting in the busfalls back if the bus suddenly starts.This is due to the inertia of rest
