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).
The force of gravity acting on an object is also that object's weight. When you step on a scale, the scale reads how much gravity is acting on your body. The formula to determine weight is [source: Kurtus ]: weight = m * g.where m is an object's mass, and g is the acceleration due to gravity.Acceleration due to gravity on Earth, is 9.8 m/sÂ² -- it never changes, regardless of an object's mass.here G is the gravitational constant, m1 and m2 are the masses of the two objects for which you are calculating the force, and d is the distance between the centers of gravity of the two masses. G has the value of 6.67 x 10E-8 dyne * cm 2 /gm 2.
