Unformatted text preview: The laws of physics are invariant under a change of inertial frame. The laws of physics have the same form in all inertial frames. It is impossible to detect uniform motion. Second Postulate of Classical Physics (Galilean Transformation): • The O and O' frame are related by the Galilean Transformation. z z y y t V x x t t ′ = ′ = ′ + ′ = ′ = z z y y Vt x x t t = ′ = ′ − = ′ = ′ Newton’s Equation: In O-Frame In O'-Frame a M F r r = ' ' a M F r r = but ' a a r r = and hence ' F F r r = and hence all observers agree. Galilean invariance implies Newton’s equations of motion! y x z y' z' x' V Mass M O O' force Assume M = M'!...
