Personally I indicate vectors as a putting bar on a letter, but some people just underline it or put an arrow above it. What's your way of doing so?

If we're going to go down that route, there is Dirac notation [itex]|\psi\rangle[/itex]. (Oh, this isn't the Quantum Physics forum.)robphy said:Surprised no one chimed in with "use an [abstract] index": ##v^a##

A vector is a mathematical quantity that has both magnitude and direction. It is important because it helps us understand and describe movement, forces, and other physical quantities in the real world.
Some common ways to indicate a vector include using an arrow above the symbol, writing the symbol in bold text, or using a hat symbol (^) above the symbol.
Yes, vectors can be represented graphically using arrows. The length of the arrow represents the magnitude of the vector, and the direction of the arrow represents the direction of the vector.
To add or subtract vectors, you can use the head-to-tail method, where the tail of one vector is placed at the head of the other vector. The resulting vector is the one drawn from the tail of the first vector to the head of the second vector. You can also use mathematical equations to add or subtract vectors.
A vector has both magnitude and direction, while a scalar only has magnitude. For example, velocity is a vector quantity because it has both speed and direction, while speed is a scalar quantity as it only has magnitude.
