What is the sign of demotion for distance and displacement.
Answers
Explanation:
Summary
Displacement…
is a vector measure of the spatial interval between two locations measured along the shortest path connecting them.
may be described…
with a magnitude (∆s) and a direction (θ) or
as a set of components (∆x, ∆y).
is represented by the symbol ∆s (boldface).
is synonymous with a change in position.
Distance…
is a scalar measure of the spatial interval between two locations measured along the actual path connecting them.
has magnitude only.
is represented by the symbol ∆s (italic).
Symbols
The origin of the symbols for displacement (∆s) and distance (∆s) is spatium, the Latin word for space (like the space between two locations).
The relation of distance to displacement
The distance traveled to get from one location to another is always greater than or equal to the magnitude of the displacement between the two locations.
∆s ≥ |∆s|
Distance approaches the magnitude of displacement as distance approaches zero.
∆s → 0 ⇒ ∆s → |∆s|
The SI unit of distance and displacement is the meter [m].
The meter is one of the seven base units of the International System of Units.
