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).
2) mg = (G M m) / d2 g = (G M) / d2 â¦(3) Where F is The force of gravity , G is gravity constant , M is the mass of earth , m is the mass of the object , d is the distance between earth & the object , a is acceleration and g is gravitation from equation 3 since (G) and (M) are constant it's clear that (g) depends only on the distance (d) between Erath and the object and do not depend on the mass of falling object.
