Gravity and Orbits: Gravity And Orbits Phet Worksheet Answer Key Pdf

Gravity is a fundamental force in the universe that attracts objects with mass towards each other. It plays a crucial role in shaping the orbits of celestial bodies, from planets revolving around stars to galaxies bound together in clusters.

Relationship between Gravity and Orbits, Gravity and orbits phet worksheet answer key pdf

Gravity is the force that keeps planets in orbit around the sun. The greater the mass of the central body, the stronger the gravitational pull, and the tighter the orbit of the revolving object. Conversely, the farther an object is from the central body, the weaker the gravitational force, and the more elliptical the orbit.

Examples of Gravity’s Influence on Orbits

• The Earth’s orbit around the sun is nearly circular due to the strong gravitational pull of the sun.
• Comets have highly elliptical orbits because their distance from the sun varies greatly.
• The dwarf planet Pluto has an eccentric orbit due to its gravitational interactions with Neptune.
