You are driving north on a highway. Then, without changing speed, you round a curve and drive east. Does your velocity change?

You are driving north on highway then, without changing speed,you round a curve and drive east. Does your velocity change?
To determine if your velocity changes, we need to understand what velocity means. Velocity is a vector quantity that describes both the speed and direction of an object's motion. In this case, you are driving north, which means your velocity has a direction associated with it.
When you round the curve and start driving east, your direction changes. Thus, your velocity changes. Even though your speed (the magnitude of your velocity) remains constant since you haven't changed your speed, the change in direction means that your velocity has changed.
To visualize this, imagine that you are driving on a road facing north with a velocity vector pointing north. As you round the curve, your velocity vector should change to point east, indicating a change in velocity.
