CHEM 111: Units of Measurement & Uncertainty

Kinetic Energy

The energy of motion possessed by any moving object or particle, such as moving molecules or macroscopic objects.

Potential Energy

Energy stored by virtue of an object's position or structural arrangement, such as chemical bonds or an object at a height.

Electrostatic Potential Energy

Potential energy resulting from electrical attraction or repulsion between charged particles, where bringing opposite charges closer lowers potential energy and increases stability.

Chemical Energy

A form of potential energy stored in the structural arrangement of atoms and electrons, where more stable chemical bonds correspond to lower potential energy.

SI Base Units

The seven internationally agreed fundamental units of scientific measurement: meter ($\text{m}$), kilogram ($\text{kg}$), kelvin ($\text{K}$), second ($\text{s}$), mole ($\text{mol}$), ampere ($\text{A}$), and candela ($\text{cd}$).

Derived Units

Units created by combining SI base units algebraically, such as speed ($\text{m/s}$), volume ($\text{m}^3$), density ($\text{kg/m}^3$), and energy ($\text{J}$).

Scientific Notation

A system of expressing numbers in the form $a \times 10^n$, where $$1 egin{equation*} ext{ aisebox{-0.5ex}{ extless}}egin{array}{c}=[-1.8ex] ext{ aisebox{0.5ex}{ extless}}egin{array}{c} ext{ or
