Key Stage 3
Meaning
Gravitational Field Strength is the force on an object per kilogram in a gravitational field.
About Gravitational Field Strength
- On Earth gravitational field strength is roughly 10 Newtons for each kilogram of mass (10N/kg).
- Different objects have different gravitational field strengths.
