Question

A body whose speed is constant -

• A. must be accelerated
• B. may be accelerated
• C. never be accelerated
• D. None of these

Answer 1

The correct option is B may be accelerated

A body is accelerated when its velocity is variable. Since velocity is a vector quantity, its magnitude may be constant, but its direction may change. Hence, speed may be constant but can accelerate. Example, uniform circular motion.
