Check understanding
- States that gravity is a universal attractive force acting between all objects with mass
- Explains that orbital motion occurs because gravity continuously deflects the path of the orbiting object
- Compares gravitational field strength on different planets and explains how this affects weight
“If your child was asked why the Moon doesn't fly off into space but also doesn't crash into Earth, could they explain that gravity is constantly pulling it into a curved path — like swinging a ball on a string?”
