Key Topics
Gravity
- Definition: A fundamental force by which objects with mass attract one another.
- Role in Universe: Crucial in forming stars, planets, and galaxies, and in keeping planets in orbit around the sun.
Gravitational Field Strength
- Definition: The force acting on a mass due to gravity.
- Unit of Measure: Measured in newtons per kilogram (N/kg).
- Earth's Gravitational Strength: Approximately 9.8 N/kg.
Weight
- Definition: The force exerted by gravity on an object.
- Formula: Weight = Mass x Gravitational Field Strength.
- Variation with Location: Weight can vary depending on the gravitational field strength of the location.
