Concepts Of Physics MCQ Edition [Volume 2]PhysicsThe Special Theory of Relativity
Identify the correct statements concerning relativistic and nonrelativistic equations:
Options
- AThe equations of special relativity are not valid for small speeds.
- BNonrelativistic equations never produce exact results.
- CNonrelativistic equations yield exact results at small speeds.
- DThe equations of special relativity are valid across all speeds.
Correct answer
D. The equations of special relativity are valid across all speeds.
Step-by-step solution
The equations of special relativity are fundamental and apply to all speeds v Nonrelativistic equations are approximations of relativistic equations obtained by taking the limit v c . Since they are approximations, they never produce exact results for any non-zero speed, although the deviation from exact results is negligible at small speeds. Thus, the correct statements are that nonrelativistic equations never produce exact results and the equations of special relativity are valid across all speeds.
