All motions are:
Correct answer: B. Relative
- A. Absolute
- B. Relative
- C. Uniform
- D. None of these
Explanation
"All motions are relative."This statement reflects the principle of relativity in physics, which is a fundamental concept introduced by Albert Einstein in his special theory of relativity. The concept of motion is relative, meaning that the motion of an object can only be described in relation to another object. There is no absolute state of rest or absolute state of motion; it all depends on the observer's frame of reference.

About Dawn of Modern Physics
Classical physics cannot explain blackbody radiation and related observations, leading to Planck’s quantum theory, in which energy is emitted or absorbed in discrete packets. Photons provide the particle model of light, with energy and momentum linked to frequency and wavelength, including the photoelectric effect and its threshold frequency.
