A inline skater is skating around a parking lot can she have constant speed changing velocity?
Not only can she have it, she must, in order to stay on the parking lot. Velocity means speed and direction of motion. If she wants to stay on the nice icy parking lot, she absolutely must change her direction now and then. That means her velocity has to change, even if her speed doesn't. By the way, that's called 'acceleration'.
