Study Notes
Gravity and Universal Attraction
- The force with which two objects attract each other is called gravity.
- Gravity is the force that keeps the Earth in uniform circular motion around the Sun.
- The law that states every body in the universe attracts every other body with a force directly proportional to the product of their masses and inversely proportional to the square of the distance between them is the Law of Universal Gravitation.
- Gravity is a force that can act even if two objects are not connected to each other.
- The weight of a body varies from place to place due to gravity.
