Gravitational and Electric Fields - similarities and differences

 

Relationships between Gravitational and Electric Fields

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), p300). 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:
