The direction of acceleration in uniform circular motion is along the
General KnowledgePhysics
- Adirection of motion
- Btangent to the circle at the point of observation
- Cdirection of velocity
- Ddirection perpendicular to velocity
Explanation
In uniform circular motion the acceleration is centripetal, directed toward the centre of the circle — that is, along the direction perpendicular to the velocity (which is tangential). It is not along the direction of motion or velocity. The acceleration acts perpendicular to the velocity.
