Gravitational field: WAEC Physics Past Questions and Answers

What the WAEC syllabus covers in Gravitational field

Our summary: How masses attract each other, and what gravity means for weight and for escaping Earth.

• Acceleration due to gravity ($g$) ($g$ as gravitational field intensity should be mentioned, $g = F/m$.)
• Gravitational force between two masses (Newton's law of gravitation. Masses include protons, electrons and planets. Universal gravitational constant ($G$). Relationship between $G$ and $g$.)
• Gravitational potential and escape velocity (Calculation of the escape velocity of a rocket from the earth's gravitational field.)
