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).
1 F is the force of gravity (measured in Newtons, N). 2  G is the gravitational constant of the universe and is always the same number. 3  M is the mass of one object (measured in kilograms, kg). 4  m is the mass of the other object (measured in kilograms, kg).
