# Gravitational Potential

#### Input data

$$Mass\ m = 45\ Kg$$ $$Gravity\ g=6\ m/s^2$$ $$Height\ g=15\ km$$

#### Solution :

$$PE=4050000\ J$$

#### Formula

$$PE_g = mgh$$ Where:
PEg or PE = gravitational potential energy
m = mass of an object
g = acceleration due to gravity
h = height of the object

#### Input data

$$Potential\ Energy\ PE = 4050000\ J$$ $$Gravity\ g=45\ m/s^2$$ $$Height\ h=32\ km$$

#### Solution :

$$m=2.8125\ Kg$$

#### Formula

$$m = \dfrac{PE_g}{gh}$$ Where:
PEg or PE = gravitational potential energy
m = mass of an object
g = acceleration due to gravity
h = height of the object

#### Input data

$$Potential\ Energy\ PE = 4050000\ J$$ $$Mass\ m=45\ kg$$ $$Height\ h=32\ km$$

#### Solution :

$$g=2.8125\ m/s^2$$

#### Formula

$$g = \dfrac{PE_g}{mh}$$ Where:
PEg or PE = gravitational potential energy
m = mass of an object
g = acceleration due to gravity
h = height of the object

#### Input data

$$Potential\ Energy\ PE = 4050000\ J$$ $$Mass\ m=45\ kg$$ $$Gravity\ g=32\ m/s^2$$

#### Solution :

$$h=2.8125\ km$$

#### Formula

$$h = \dfrac{PE_g}{mg}$$ Where:
PEg or PE = gravitational potential energy
m = mass of an object
g = acceleration due to gravity
h = height of the object
