Description

A 5-step lesson. Step 1: 'Gravitational field strength g = F/m = GM/r² (force per unit mass at a point). It's a vector pointing toward the mass creating the field.' Units: N/kg or m/s². Step 2: 'Gravitational potential V = -GM/r (energy per unit mass at a point). It's a scalar, always NEGATIVE (beca
