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.
