If the car is experiencing a change in velocity, the car is accelerating
Explanation:
Speed is a scalar quantity (defined by magnitude and not by direction) while Velocity is a vector quantity (has a magnitude and a direction).
Magnitude of the velocity vector is the instantaneous speed while travelling and direction of the velocity vector will keep changing with change in position because it is tangential to the circle.
This means with every change in direction the travels on the circular track the speed is constant but the velocity would keep changing.
Acceleration is simply a change in velocity over time, this means if the car is experiencing a change in velocity, there is acceleration.
A figure of speech is a figure of speech in which a word or phrase is applied to an object or action to which it is not literally applicable. An example of a metaphor would be "Rollercoaster of emotions" which means, that they are experiencing a lot of good and bad things
