Can an object have a varying speed it its velocity is constant?

Answer 1

Of course, since velocity is a vector quantity and speed is a scalar quantity, velocity has something speed does not: direction. Thus, an object can travel at the same speed by has a changing direction of movement, and therefore a changing velocity. For instance, a ball on a string moving in a circle at the same speed is constantly changing its velocity, which results in its path of motion.
Yes. Velocity is (speed and direction of motion). If direction changes, then velocity

changes, even if speed is constant.

Examples:

-- Car going around a curve at a constant speed has changing velocity.

-- Anything traveling a circular path at a constant speed has changing velocity.

Answer 2

Yes. Velocity combines the descriptions of speed and direction. If the direction

of motion is changing, like moving along a curve or bouncing off a wall, then the

velocity is changing, even though the speed may be constant.

Answer 3

No, velocity is a vector quantity and measures both speed and direction. If the velocity of an object is constant then that would also mean the speed would stay constant.

Answer 4

No. Speed is the magnitude of the velocity. If either or both the speed and direction vary, the velocity is not constant.
