Physical Quantities
Card 1: What are physical quantities?
Physical Quantities
- A physical quantity is a quantity that can be measured.
- A physical quantity can be divided into base quantity and derived quantity.
Card 2: What are base quantities?
Base Quantities
Base quantities are quantities that cannot be defined in term of other physical quantities.
Card 3: State the 5 base quantities and their SI unit
5 Base Quantites
| Quantity | Name of Unit | Symbol of Unit |
| Length | metre | m |
| Time | second | s |
| Temperature | Kelvin | K |
| Mass | kilogram | kg |
| Current | Ampere | A |
Card 4: What is derived quantities?
Derived Quantities
A derived quantity is a Physics quantity that is not a base quantity. It is the quantities which derived from the base quantities through multiplying and/or dividing them.
Card 5: What is derived unit?
Derived Unit
The derived unit is a combination of base units through multiplying and/or dividing them.
Card 6: What are prefixes?
Card 7: What are scalar quantities?
Scalar Quantities
- Scalars are quantities which are fully described by a magnitude alone.
- Examples of scalar quantities are distance, speed, mass, volume, temperature, density and energy.
Card 8: What are vector quantities?
Vector Quantities
- 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.
