Question

# A body whose speed in a particular direction is constant

A
Must be accelerating
B
Must be retarding
C
Has a constant velocity
D
All the above

Solution

## The correct option is C Has a constant velocityIf a body with constant speed is travelling in the same direction(i.e. it is not changing its direction) then its velocity is constant and so its acceleration will be zero. But if the object is changing its direction then its velocity is also changing and so it possesses the acceleration .A body whose speed in a particular direction is constant has a constant velocityPhysics
