    Study Notes

    Gravity as a Fundamental Force

    • Gravity is a fundamental force shaping the universe, influencing everything from planetary orbits to star formation.
    • Its strength is dependent on the mass of objects and the distance between them.

    Newton's Theory of Gravity

    • Newton's theory explained how gravity affects celestial bodies (e.g., planets orbiting the sun).
    • Published in 1687, this theory described gravity as a force.

    Einstein's Theory of General Relativity

    • Einstein revolutionized understanding of gravity.
    • Proposed gravity isn't a force, but a curvature of spacetime caused by mass and energy.
    • This theory has significant implications like the existence of black holes.

    Gravity in the Film "Gravity"

    • The film "Gravity" (2013) showcases gravity's powerful effects in space.
    • It depicts the struggles of astronauts facing catastrophic events in orbit.
    • The film's visuals and realism highlight gravity's importance in space exploration.
    • While fictional, the film powerfully illustrates gravity's influence.
