According to Levin, Newton's laws of motion work have become outdated and no longer used.

• A. True
• B. False
• C. Only in relativistic scenarios
• D. Only in quantum regimes

Answer: (B)

Newton's laws remain the practical backbone of classical mechanics and are far from outdated. They describe how forces produce accelerations, and in everyday situations—as well as in many astrophysical problems where speeds are well below light and gravity isn’t extreme—they provide accurate and usable results. Levin's claim overstates things: Newton's laws are still essential and routinely used as the starting point for modeling motion. Only in regimes where relativity matters—high speeds or strong gravity near massive bodies—or in quantum-scale dynamics do we switch to more advanced theories, though Newtonian results often serve as a good approximation. So the statement is not correct; Newton's laws are still used today.
