# Question #d79e2

#### Answer:

Well...this one is tricky indeed!

#### Explanation:

Velocity is a vector so you have a modulus (the value with units) AND a direction;
so, velocity can be uniform in modulus (say, $3.0 \frac{m}{s}$) but change in direction (i.e., in circular motion): this change implies an acceleration that in case of circular motion (uniform) is called Centripetal Acceleration.

Hope it helps!
