What is Mechanics ?
Ans. The branch of physical science dealing with the
behaviour of matter under the action of forces.
Q. What is the difference between
Newtonian Mechanics and Quantum Mechanics?
Ans. Newtonian Mechanics is based on Newton's laws of
motion and provides an accurate means of determining the motions of bodies
possessing ordinary velocities.
Quantum
Mechanics is a method of interpreting physical phenomena occurring on a very
small scale (e.g., the motion of electron and nuclei within atoms).
