Question

Define displacement. State its unit.

• A. Displacement is a vectorial sum of the distances travelled by the body. The standard unit of displacement in the International System of Units ( SI ) is the kilometer (km).
• B. Displacement is total distance travelled by the body. The standard unit of displacement in the International System of Units ( SI ) is the kilometer (km).
• C. Displacement is total distance travelled by the body. The standard unit of displacement in the International System of Units ( SI ) is the meter (m).
• D. Displacement is a vectorial sum of the distances travelled by the body. The standard unit of displacement in the International System of Units ( SI ) is the meter (m).

Answer 1

The correct option is D Displacement is a vectorial sum of the distances travelled by the body. The standard unit of displacement in the International System of Units ( SI ) is the meter (m).

Displacement (symbolized d or s ), is a one-dimensional quantity representing the separation between two defined points. It is the shortest distance from the initial to the final position of a point P and is a vector quantity that has a direction.
The standard unit of displacement is the meter (m).
