Newton’s 1st law: Objects will remain at rest or moving at a constant velocity unless acted upon by an unbalanced force.

Newton’s 2nd law: F=ma

Newton’s 3rd law: All forces come in pairs equal in magnitude and opposite in direction.

1st postulate of special relativity: The laws of physics are the same in all inertial frames of reference.

2nd postulate of special relativity: The speed of light in a vacuum is the same as measured by all observers in any inertial frame of reference.
