## Study Notes

### Physical Quantities and Units

• A scalar physical quantity has only magnitude, whereas a vector physical quantity has both magnitude and direction.
• A physical quantity that consists of a magnitude and unit is called a measurable quantity.

### Units

• A fundamental unit is a unit that cannot be expressed in simpler units, for example, meter (m) for length.
• The system of units that uses foot, pound, and second as the base units for length, mass, and time respectively is the Foot-Pound-Second (FPS) system.

### Derived Units

• The Newton (N) is a derived unit, as it is derived from fundamental units, specifically, N = kg·m/s².

### SI System

• What sets the SI (International System of Units) apart from earlier systems like CGS (Centi-Gram-Second) and FPS is that SI is a decimal-based system, making conversions easier and more logical.
