D.1.5—Gravitational field lines Topic Practice
Practise reading and drawing gravitational field-line diagrams, showing direction towards masses and how spacing represents changing field strength.
How this is tested
- interpret wider field-line spacing as weaker gravitational field strength at greater distance from a planet
- draw radial field lines with arrows pointing inward, or force arrows towards each attracting star on a diagram
