Answer:
In addition to magnitude and direction,
each vector also has a definite location in space. For example, a velocity
vector has definite location at every point of uniform circular motion.
A vector can vary with time. For
example, increase in velocity produces acceleration.
Two equal vectors and 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.
