Some quantities are scalar quantities and others are vector quantities. Which of the following is a scalar quantity?

A scalar quantity is fully described by its magnitude (size) alone. A vector quantity requires both magnitude and direction. - **Displacement** is the overall change in position, including direction (e.g., 50m North). It is a vector. - **Distance** is how far an object has moved, without regard to direction (e.g., 50m). It is a scalar. - **Force** has a size and a direction in which it acts (e.g., 10N downwards). It is a vector. - **Speed** is how fast an object is moving (e.g., 10 m/s). It is a scalar. - **Velocity** is speed in a given direction (e.g., 10 m/s East). It is a vector.
