When describing velocity what should be included?

When describing velocity, the following components should be included:

1. Magnitude: Velocity is a vector quantity, meaning it has both magnitude (speed) and direction. The magnitude of velocity refers to the speed of the object.
2. Direction: Velocity is not just about how fast something is moving but also in which direction. The direction can be described using words (e.g., north, southeast) or specified in terms of angles or coordinates.
3. Unit: The unit of velocity depends on the system of measurement used. In the International System of Units (SI), the unit of velocity is meters per second (m/s).

Mathematically, velocity (v) can be expressed as:

v= Δr \ Δt

​Where:

• Δr is the displacement (change in position),
• Δt is the change in time.

Velocity provides information about the rate of change of position of an object with respect to time and its direction of motion.
