When do Newton's laws begin to break down in their accuracy for describing motion?

Newton's laws of motion are powerful tools for understanding the dynamics of everyday objects under typical conditions. However, they begin to break down when considering scenarios involving objects moving at or near the speed of light. At these velocities, the effects of relativity become significant and can no longer be accurately described using classical mechanics.

As objects approach light speed, time dilation and length contraction occur, altering the way we perceive motion and force. This necessitates a transition to Einstein's theory of relativity, which provides a more comprehensive framework for understanding physics at high velocities. Thus, the statement that Newton's laws fail to accurately depict motion at speeds close to light highlights the limitations of these laws in extreme conditions, making it the appropriate choice in this context.
