5.6.5 Velocity

infoNote

Velocity tells us the speed of an object in a given direction (vector quantity).

lightbulbExample

Example: 20m/s South.

infoNote

Calculation

Velocity is calculated in the same way as speed, but the direction should also be stated.

\text{Velocity (v)} = \frac{\text{distance (s)}}{\text{time (t)}}

Determine the direction in which the object moves using a compass (NESW).

Velocity in Objects Moving in a Circle

infoNote

If an object moves at a constant speed in a circle, then its velocity is constantly changing even though its speed is constant. This also includes objects moving around a part of a circle, e.g., moving around a corner.
