Energy Vault, Gravity Power, and their competitors seek to use the same basic principle—lifting a mass and letting it drop—while making an energy-storage facility that can fit almost anywhere.
Use the following formula to calculate the gravitational force between any two objects: F = GMm/R². where: F — Gravitational force, measured in newtons ( N) (our force converter can convert it to other units). It is always positive, which means that two objects of a certain mass always attract (and never repel) each other;

To calculate the amount of potential energy stored in a 1-ton weight (2000 pounds) lifted to a height of 20 feet, Potential Energy (PE) = mass × acceleration due to gravity × height. 1 ton = 2000 pounds = 2000 lbs Height = 20 feet.
The Formula for Calculating Potential Energy. Even though you are calculating something as complex as potential energy, the formula is straightforward. The hardest part is getting your input data. Potential Energy Gravity = M x H x G M = Mass H = H G = Gravitational Field Strength (on Earth, it''s 9.81 m/s²) Attention physics students!
Sharing is Caring. The formula for buoyant force is: (B) = ρ V g. ρ = Density of Fluid (We used density of the air because the balloons were afloat, not submerged) V = Displaced Volume. g = 9.8 (gravity) Density of air (ρ)= 1.225 kg/m3. Volume of gas filled balloon:= 0.40031998748547 m3.
The simplest formula is : GPE = m*g*h. Where : GPE = gravitational potential energy (joules j) m = mass in kilogram (kg) g = acceleration due to gravity (m/s²) h = change in height h rather than the usual Δh (Note that h is positive when the final height is greater than the initial height, and vice versa), in meters (m)
