What is gravitation?
A push or pull acting on an object
The force of attraction between objects with mass
Responsible for interactions between charged particles
Governs processes like radioactive decay
What defines weightlessness?
Experiencing no force due to gravity
Experiencing a push or pull on an object
The force of attraction between charged particles
The force that binds protons and neutrons within an atom's nucleus
