Do newtons laws apply? Not at high velocities, am I correct? Well, the earth travels around the sun at 100,000 km per hour. Is that not high velocity? Well , it is said that Newtons laws don't apply at high velocities, or is size and proportion involved?
Yes, Newton's laws apply for macroscopic systems. It's just that we have to use relativistic versions of those laws at high speeds. Of course, the relativistic versions are correct at low speeds too.

I am. Stop using Physics Forums as a crackpot chat site.
