Study Notes
Physics Fundamentals
- Physics is the study of matter and energy and their relationships.
- Fundamental quantities are basic quantities that are independent of any other quantities.
Fundamental Quantities
- Examples of fundamental quantities include:
- Mass (M)
- Amount of substance (A)
- Length (L)
- Luminous intensity (L)
- Time (T)
- Temperature (T)
Derived Quantities
- Derived quantities are dependent on other quantities.
- Examples of derived quantities include:
- Force
- Energy
- Density
- Speed
- Velocity
- Volume
- Acceleration
- Power
- Pressure
- Moment
- Momentum
Scalar Quantities
- Scalar quantities have magnitude but no direction.
