Velocity (Edexcel GCSE Physics Combined Science): Revision Notes

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

Calculation

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

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

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.
