a body moving at a constant speed accelerates when it is in
- rectilinear motion
- translational motion
-
circular motion
- vibrational motion
The correct answer is: C
Explanation
A body moving at a constant speed can accelerate if it is in circular motion. This is because acceleration is a change in velocity, and velocity is a vector quantity, meaning it has both magnitude (speed) and direction. In circular motion, the direction of the velocity is constantly changing, even if the speed is constant, so there is acceleration.
