Newtonian physics are dead-on and totally still used when it comes to objects that fit our sphere of size and mass. newtonian physics nearly perfectly can explain most of the Universe visible to us. Where it fails, and this is where physics find themost interesting projects to work on, is when we deal on a super scale, of either super massive (black holes, galactic centers, etc) or the super small (the "quantum" world)
Newton's laws are always valid when it comes to our scale.
