Study Notes
- "Petere" in Latin is discussed in connection to the letter "p" for momentum.
- Momentum is defined as mass times velocity, a vector quantity with magnitude and direction.
- Uppercase "P" represents power, while lowercase "p" symbolizes momentum; lowercase Greek letter "rho" is used for density.
- The units for momentum are kilograms times meters per second, without a specific name.
- Zero momentum is achieved with zero velocity, highlighting the correlation between momentum and velocity.
