Question

In uniform circular motion, the velocity vector and acceleration vector are

  1. Perpendicular to each other  
  2. Same direction  
  3. Opposite direction  
  4. Not related to each other  

The correct answer is: Perpendicular to each other


    Because velocity is always tangential and centripetal acceleration is radial.
