Share. Covalent Bond Definition: A covalent bond is a chemical link between two atoms in which electrons are shared between them. Examples: There is a covalent bond between the oxygen and each hydrogen in a water molecule (H 2 O).Each of the covalent bonds contains two electrons-one from a hydrogen atom and one from the oxygen atom. Both atoms share the electrons.Return to the Chemistry Glossary Index.xamples: There is a covalent bond between the oxygen and each hydrogen in a water molecule (H 2 O).

G-Force is Gravity Force or simply the force due to gravity. Note that one G is only equal to 9.8 m/s^2 on Earth since the gravitational constant changes depending on where in the universe you're at (e.g. on another planet).
g-force (with g from gravitational) is a measurement of the type of acceleration that causes weight. Despite the name, it is incorrect to consider g-force a fundamental force, as g-force (lower case character) is a type of acceleration that can be measured with an accelerometer.
