These calculators can be used to generate data using **density**, **volume**, **radius** and **force**.

Calculate the **force** given the **density** and **volume** of two objects and a **radius**.

F = kDVdv/r^{2}

Calculate the first **density** given the first **volume**, the second **density** and **volume**, **force** and **radius**.

D = Fr^{2}/kVdv

Calculate the first **volume** given the first **density**, the second **density** and **volume**, **force** and **radius**.

V = Fr^{2}/kDdv

Calculate the second **density** given the first **density** and **volume**, the second **volume**, **force** and **radius**.

d = Fr^{2}/kDVv

Calculate the second **volume** given the first **density** and **volume**, the second **density**, **force** and **radius**.

v = Fr^{2}/kDVd

Calculate the **radius** given the **density** and **volume** of two objects and the **force** between them.

r = √[kDVdv/F]
