| Front | what causes gravitational fields |
| Back | a mass |
| Front | gravitational fields' strength is.. |
| Back | directly proportional to the size of mass inversely proportional to the separation (radius)^2 |
| Front | Electrostatics (2) |
| Back | Electric charges are stationary and at rest.Charges @ rest feel a force (attraction/ repulsion) from others around them |
