Space Physics [Triple Only]

Simple explanation

Gravity provides the centripetal force for orbital motion.

Analogy or example

A stable orbit happens when gravity constantly changes the direction of motion.

Misconception trap

Planets orbit because there is no force acting on them.

Real-world relevance

Solar system and stars connects equations and models to technology, transport, energy and space.

Simple explanation

Light from distant galaxies is shifted to longer wavelengths.

Analogy or example

More distant galaxies generally show greater red shift.

Misconception trap

Red shift means galaxies are getting colder.

Real-world relevance

Red shift connects equations and models to technology, transport, energy and space.

Vocabulary check

shift, light, distant, galaxies, shifted

Simple explanation

Life cycle of stars sits inside Space Physics [Triple Only], so learn the core definition and the exam example that usually comes with it.
