Can an object have constant speed but variable velocity?

1.	Can an object have constant speed but variable velocity?
Answer» No, in order for the velocity to be constant, the speed has to be constant.Speed is a scalar, meaning that it is just a number. (A car goes 50 miles per hour).Velocity is a vector, which indicates that it needs a measure of its displacement and a direction.(A car is going 50 mph to the east). A body can have a constant speed but a changing velocity because the direction can change while the speed is constant. (A car goes 50 mph around a roundabout).However, a body can not have a constant velocity with a changing speed.A car can not be slowing down yet still be going the same speed and direction
