# Forces

## Scalar

Scalar quantities only have a **magnitude** or a size.

Examples of scalar quantities include:

- Energy
- Distance
- Speed
- Area
- Volume
- Speed
- Mass
- Temperature

## Vector

Vector quantities have a **magnitude** and an associated **direction**.

Examples of vector quantities include:

- Displacement
- Velocity
- Acceleration
- Momentum
- Force
- Weight

Vectors can be represented by an arrow. The **length** of the arrow represents the **size** and the **direction** of the arrow shows the **vector quantity**.

The difference between them is the fact that vector quantities have a direction, where scalar quantities do not.

- Define a scalar quantity
- Your answer should include: size / magnitude
- Are the following quantities scalar or vector? Force, weight and acceleration
- vector
- Define a scalar quantity
- Your answer should include: size / magnitude

Explanation:*Has size or magnitude*
