Study Notes
Energy and Pressure Definitions
- Leibniz originally defined energy as "the capacity for doing work," emphasizing the relationship between energy and mechanical work.
Units of Pressure
- The unit for pressure according to the International System of Quantities (SIQ) is the Pascal (Pa).
- Standard unit for pressure is also the Pascal, derived as one Newton per square meter.
Dimension of Speed
- Speed is expressed in terms of dimensions as length divided by time, represented as [L][T]⁻¹, where [L] denotes length and [T] denotes time.
Unit of Energy
- The unit for energy according to the International System of Quantities (SIQ) is the Joule (J).
- One Joule is defined as the amount of energy transferred when a force of one Newton acts through a distance of one meter.
