Is constant speed constant velocity?
No. Velocity includes a direction vector, which speed does not have.
How can a vehicle at the same time have a constant speed but changing velocity?
A vehicle can have a constant speed but changing velocity if it is moving in a curved path. In this case, the direction of the vehicle is changing, causing its velocity to change even though its speed remains constant. This is because velocity is a vector quantity that includes both the speed and direction of motion.
The main difference between speed and velocity?
The main difference between speed and velocity involves direction. Velocity involves an object moving in a particular direction.
Can an object have a constant speed and a varying velocity?
Yes, an object can have a constant speed but varying velocity if it changes direction while moving at that speed. Velocity includes both speed and direction, so if an object is moving in a straight line at a constant speed but changing direction, then its velocity is constantly changing even though its speed remains the same.
Why is velocity a vector quantity?
Velocity refers to both speed and direction. A vector refers to both magnitude (the speed in this case) and a direction. Speed without reference to a direction is a scalar, a magnitude without direction.
