CAIE IGCSE Physics 6.1.2.3 Strength of the gravitational field

Practise relating gravitational field strength to a planet's mass and to distance from the planet in simple Solar System contexts.

Exam points

predict how surface gravitational field strength changes for planets of different mass
explain that gravitational field strength decreases as distance from a planet increases

[Maximum number: 1]

Jupiter and the Earth are planets in our Solar System.

The gravitational field strength at the surface of the Earth is approximately $9.8 \mathrm{~N} / \mathrm{kg}$ . The gravitational field strength at the surface of Jupiter is approximately $23 \mathrm{~N} / \mathrm{kg}$ .

State one factor which causes the difference between the gravitational field strength at the surface of Jupiter and the gravitational field strength at the surface of the Earth.
