    Constant Vector
Click For Summary
A constant vector is defined as one that does not change in magnitude or direction as a specific variable, such as time, varies. It is important to note that a vector can have a constant length but still change direction, which disqualifies it from being a constant vector. For example, an object moving in a circle at a constant speed experiences acceleration due to the change in direction. Thus, the key characteristic of a constant vector is its unchanging nature in both magnitude and direction. Understanding these definitions is crucial for discussions in physics and mathematics.

What is a "constant" vector?

Please thanks

A vector that doesn't change as a pre-determined "variable" (say, for example, "time"), changes.
 


maybe it would easier to answer if you gave us some context.
 


A vector that has a constant length but changes direction would not be a constant vector. That is why an object moving in a circle with constant speed still has an acceleration.
