RELATIONSHIPS BETWEEN GRAVITATIONAL AND ELECTRIC FIELD EQUATIONS
This is an adaptation of a very helpful summary that I found in one of the first textbooks I used when I became a teacher (Revised Nuffield Advanced Science Physics, Student Guide 1 (1985), page 300). It shows how the equations for Gravitational (or Electrostatic) Force, Field Strength, Potential and Potential Energy are inter-related:
SIMILARITIES AND DIFFERENCES BETWEEN GRAVITATIONAL AND ELECTRIC FIELDS
Similar to the above, this puts equivalent equations and properties of gravitational and electric fields next to each other in a table to act as a useful summary:
