# Illustration Gravitational force (weight) acts on a mass

On a mass $$m$$ (e.g. apple) acts gravitational force (weight) $$\boldsymbol{F}_{\text g}$$ which pulls the apple towards the earth. Because of the relation $$\boldsymbol{F}_{\text g} = m \, \boldsymbol{g}$$ also the gravitational acceleration $$\boldsymbol{g}$$ points in the same direction as the gravitational force.
The magnitude $$g$$ of the acceleration vector $$\boldsymbol{g}$$ corresponds on Earth to the value: $$g = 9.8 \, \mathrm{m}/\mathrm{s}^2$$.
