Definition: Gravitational theory is a scientific idea in physics that explains how objects with mass attract each other. The strength of this attraction depends on two things: the amount of mass each object has and how far apart they are. The closer two objects are, the stronger the attraction.
In advanced discussions about physics, you might encounter variations of gravitational theory, such as: - Newton's Law of Universal Gravitation: This is a specific formulation of gravitational theory proposed by Isaac Newton. - Einstein’s General Relativity: A more advanced theory that describes gravity not just as a force but as a curvature of space-time caused by mass.
While "gravitational theory" specifically refers to the scientific concept in physics, "gravity" in everyday language can also mean seriousness or importance. - Example: "The gravity of the situation made everyone quiet."
While "gravitational theory" does not have specific idioms or phrasal verbs associated with it, you might hear expressions related to gravity, such as: - "What goes up must come down": This means that anything that rises (like a thrown ball) will eventually fall back down due to gravity. - "Fall for": To become attracted to someone or something, although this is more metaphorical.
"Gravitational theory" is an important concept in physics that describes how and why objects with mass pull on one another.
