2. Explain why centripetal acceleration changes the direction of velocity in circular motion but not its magnitude. To answer this question, I will explain what centripetal acceleration is. Centripetal acceleration is the acceleration experienced by an object moving in a circular path. It's always towards the center and changes the direction of the object's velocity. In circular motion, velocity is a vector quantity which means it has (speed) and direction. When an object moves in a circle at the same speed, its velocity changes due to the direction always changing. (centripetal acceleration) Centripetal acceleration does not affect the magnitude of the velocity because it acts perpendicular to the velocity. Instead, it constantly changes the direction of the velocity, making sure the object stays on its circular path. Without it, the object would move in a straight line next to the circle.
