What defines a scalar quantity?
It is described by magnitude or numerical value alone.
What distinguishes displacement from distance?
Displacement has a specified direction, distance does not.
How is a vector geometrically represented?
By a directed line segment with a tail and an arrowhead.
When are two vectors equal?
When they have the same magnitude and direction.
Scalar quantity: description?
Fully described by magnitude only.
Vector quantity: description?
Described by magnitude and direction.
