A vector has magnitude and direction. Does it have a location in space ? Can it vary with time ? Will two equal vectors a and b at different location in space necessarily have identical physical effects ? Give examples in support of your answer

In addition to magnitude and direction, each vector also has a definite location in space. For example, a velocity vector has definite location of every point in uniform circular motion.
A vector can vary with time. For example, increase in velocity produces acceleration.
Two equal vectors a. and b having different locations may not produce identical physical effects. For example, two equal forces (vectors) acting at two different points may not produce equal turning effects.
