Explanation

Gravitational field is region where mass experiences gravitational force. Field strength g = F/m = GM/r². On Earth surface, g ≈ 9.8 N/kg (same as m/s²).

Field lines point toward center of mass. Closer lines indicate stronger field. g decreases with altitude (proportional to 1/r²) and varies slightly with location on Earth.

Gravitational potential energy U = -GMm/r. Negative because work is done against field to increase separation. At infinity, potential is zero (reference point).
