Study Notes
Units and Measurements
- The SI unit for mass is the kilogram (kg).
Motion and Velocity
- The velocity of an object moving 80 m in 5 seconds is 16 m/s (calculated by dividing distance by time).
X-Radiation
- Wilhelm Conrad Röntgen first discovered x-radiation on November 8, 1895.
Phosphors
- The term that refers to a phosphor's ability to emit visible light when stimulated by energy is luminescence.
Radiation Protection
- One of the cardinal rules of radiation protection is "as low as reasonably achievable" (ALARA), which aims to minimize exposure to radiation.
Derived Units
- The derived unit that is the product of mass and acceleration of an object is force, measured in newtons (N).
