What are Scalar Quantities?
Scalar quantities are physical quantities which have magnitude only or numerical value but no direction.
Examples of Scalar Quantities:
Examples of Scalar Quantities are:
- Mass
- Length
- DensityDensity is the measurement of how tightly a material is packed together i.e. how closely the particles are packed in the material. The tighter the material is packed the more its... More
- Time
- Distance
- Temperature
- Speed
- Volume
- Density
- Area
- Current
Addition of Scalar Quantities:
With scalar addition, all you have to do is add the values of each scalar item to obtain the total.
Examples of Addition of scalar Quantities:
• V1 + V2 = 10 cm3 + 30 cm3 = 40 cm3
• T1 + T2 = 273 K + 100 K = 373 K
• A1 + A2 = 200 m2 + 250 m2 = 450 m2
What are Vector Quantities?
Vector quantities are those quantities that have both magnitude and direction.
Examples of Vector Quantities:
Examples of Vector Quantities are
- Force
- Gravitational field
- Momentum
- Weight
- Velocity
