1. any rule will stay in place, it will stay in place until there is strength to cause motion, and if the object is moving with uniform velocity rectilinear motion, it will continue until the voltage is subject to change direction or change speed.
2. If rule Mimi force from outside is per object will make the object motion and speed increase.
3. rule when there are lateral forces, there will be resistance to the action of the same size and has the opposite direction.
