# (Indicates a review question, which means it requires only a basic understanding of the material to answer. Questions without this designation typically require integrating or extending the concepts presented thus far.). What is centripetal acceleration? What is the direction of the centripetal acceleration of a car going around a curve?

To determine

Centripetal acceleration and its direction when a car is going around a curve.

Explanation

Introduction:

Centripetal acceleration is necessary for a circular motion to go around a curve.

Centripetal acceleration is defined as a rate of change of tangential velocity. It is a vector quantity which is required to change the direction of the tangential velocity as a car moves around a curve. According to Newton’s first law, as the car moves around the curve, we need an acceleration to change the direction of the car...
