Question

# Which of the following is a vector quantity?

- Speed
- Time
- Distance
- Acceleration

Hint:

### Vector quantity have both magnitude and direction

## The correct answer is: Acceleration

- Speed is a scalar quantity, having only magnitude and giving no information about direction. For example, 100 m\s is a speed, it tells us how fast an object is traveling, but nothing about in which direction the object is traveling. The vector counterpart to speed is velocity.
- Time is completely separated from direction; it is a scalar quantity. It has only magnitude, no direction.
- Distance is a scalar quantity with only magnitude and not a vector quantity. It means that when an object moves, the direction of the object is not considered; only the magnitude of the distance is considered.

- Acceleration is a vector quantity because it has both magnitude and direction. When an object has a positive acceleration, the acceleration occurs in the same direction as the movement of the object and the opposite is true for negative acceleration.
