Scalar Quantity

- Scalars are quantities which are fully described by a magnitude alone.
- Magnitude is the numerical value of a quantity.
- Examples of scalar quantities are distance, speed, mass, volume, temperature, density and energy.

Vector Quantity

- Vectors are quantities which are fully described by both a magnitude and a direction.
- Examples of vector quantities are displacement, velocity, acceleration, force, momentum, and magnetic field.

Example 1

Categorize each quantity below as being either a vector or a scalar.

Speed, velocity, acceleration, distance, displacement, energy, electrical charge, density, volume, length, momentum, time, temperature, force, mass, power, work, impulse.
