Summary
This source introduces Gravity as a non-contact force, defines gravitational fields and field strength, and clarifies the distinction between Mass and Weight.
Core Ideas
- Gravity acts between masses without contact.
- Weight depends on gravitational field strength and changes by location.
- Mass stays constant while weight changes between Earth, Moon, and space contexts.
- Gravity also explains orbital motion.
