What is the equation that links gravitational field strength (g), mass (m) and weight (W)?
Weight = Mass x Gravitational Field Strength, or W=mg
Weight = Mass / Gravitational Field Strength, or W=m/g
Weight = Gravitational Field Strength / Mass, or W=g/m

What is the equation that links gravitational field strength (g), gravitational potential energy (Eg), height (h), and mass (m)?
Gravitational Potential Energy = Mass x Gravitational Field Strength x Height, or Eg=mgh
Gravitational Potential Energy = Mass / (Gravitational Field Strength x Height), or Eg=m/(gh)
Gravitational Potential Energy = Mass x Gravitational Field Strength / Height, or Eg=mg/h
