Question
What is then special about Newton’s first law if it is derivable from Newton’s second law?
✓
Answer
- Newton’s first law shows an equivalence between the ‘state of rest’ and ‘state of uniform motion along a straight line.’
- Newton’s first law of motion defines force as a physical quantity that brings about a change in ‘state of rest’ or ‘state of .uniform motion along a straight line’ of a body.
- Newton’s first law of motion defines inertia as a fundamental property of every physical object by which the object resists any change in its state of rest or of uniform motion along a straight line.
Due to all these reasons, Newton’s first law should be studied.
