Denotes **gravity** in mathematical notation.

Specifically, g is the acceleration due to the local gravitational field - the force exerted by the Earth on a sky diver in free fall, for example.

**The sky diver experienced a force of 5 g. **(not "5 g's")

g is measured in metres per second per second (m/s^{2}) and has a value of 9.81 m/s^{2} on Earth.

Not to be confused with **G.**
