    Yes, their velocity can take different directions while the magnitude remains the same.

    Velocity has both magnitude and direction and holding one constant does not affect the mutability of the other.

    Yes.It's only possible in case of rotational motions.The body rotates at constant speed but due to cnage in direction the velocity changes.

    let us talk about it in simple terms
    vector quantity- are the quantities which have magnitude & direction-velocity is a vector quantity because it has both
    scaler quantity- are the quantities which have magnitude but do not have the direction- speed is scaler because it has the magnitude but do not have the direction
    so if the speed is constant & object keeps on changing the direction then velocity will keep on changing , like if you rotate an object tied with rope at one end at constant speed,since the direction is cganging contineously so does the velocity
    Eh.. well I could not make it that simple rather more boring?

    yes, velocity has a direction speed doesn't. so the velocity of something could change while the speed stays the same

    Speed is relative, so yes, as long as you're comparing "apples" to "oranges".

    For example, if my car is traveling 55 MPH, that is relative to the earth. The earth is spinning at one rotation per day, and is zooming around the sun at 66,000 MPH. Our solar system is traversing the galaxy, which is moving in an expanding universe. So my constant speed of 55 MPH could still mean that my car is going a little faster or slower around the sun at any given moment, depening on gravitational pulls, etc.

    it could be said that " velocity= speed + direction" and velocity is a vector quantity.if speed is constant but direction is changing so velocity is changing. this is the case with uniform circular motion.
