    Study Notes

    Gravity in Our Solar System

    • Acceleration due to gravity varies on each planet in the solar system
    • On Earth, objects in free fall accelerate at approximately 9.8 m/s^2
    • Newton's universal law of gravitation states that gravity is directly proportional to mass and inversely proportional to the square of the distance between the objects
    • Objects with small masses have weak gravitational fields, while those with large masses have strong gravitational fields
    • In the early solar system, objects collided frequently, forming fewer, more massive objects through the process of accretion
    • The more massive object accelerates less in response to gravitational force
    • The sun's strong gravitational field causes planets to orbit it, and moons to orbit planets
    • Planets, moons, and other objects orbit in elliptical paths due to gravity
    • Planets have gravity because they have mass, and everything with mass has a gravitational field
    • The force of gravity decreases drastically with increasing distance between objects
    • Gravity impacts the shapes of planets and stars, causing them to be roughly spherical
    • Radial gravitational attraction pulls objects inward toward the center of mass, resulting in spherical shapes for planets and stars
