Newton's first law states: If an object is not subjected to any external force or the net external force acting on it is zero, then the object will remain in its current state of motion, either at rest or moving at a constant velocity. We can get the formula describing the relationship between the position and velocity of an object: v = ds / dt because: ds = s' - s then we can obtain: s' = s + dt * v v: object velocity ds: displacement dt: time interval s': updated position s: position
