Any physical quantity which has both direction and magnitude is called a vector. A quantity must also obey the 'Triangle law of vector addition' to be called as a vector.
For example displacement is a vector, u can say a person moved 5 km (magnitude) along west(direction). But electric current is not a vector, it has magnitude and its direction is from +ve terminal to -ve terminal but it doesn't obey triangle law. Rather currents are added as scalars.

is it testabel or good
random in science terms means random duhhh. :) random is random in every language or subjects
it means to move something
it means to describe what you did
Yes, a vector can be represented in terms of a unit vector which is in the same direction as the vector. it will be the unit vector in the direction of the vector times the magnitude of the vector.

A vector is a physical magnitude where not only a number is important, but also an associated direction. This is commonly used (for example) for velocity, acceleration, force, and many others.
