4.13: Solar System Gravity Forces Cheat Sheet
- Newton's Law of Universal Gravitation - Imagine every object in the universe giving a friendly tug on every other object! This law tells us that the pull between two masses depends on both their weights and the square of the distance separating them, summed up neatly in F = G·m·m₂/r². Open Text BC
- Gravitational Constant (G) - This tiny but mighty number (6.674×10❻¹¹ Nm²/kg²) is the glue that makes Newton's formula work. Without G, we'd have no way to turn mass and distance into an actual force - it's the cosmic conversion factor! Open Text BC
- Gravitational Force Between Planets - Planets don't just float around; they pull on each other through space. For example, Earth and Moon share a gravitational handshake of about 2×10²❰ N, showcasing how even distant bodies can exert massive forces. GeeksforGeeks
- Surface Gravity - Why do you weigh less on Mars? Because each planet's gravity depends on its mass and radius. Earth's surface gravity is about 9.8 m/s², while Mars only manages around 3.7 m/s² - gravity's way of giving you a lighter workout. Wikipedia
- Gravitational Potential Energy - Moving an object against gravity stores energy, measured by U = - G·m·m₂/r. This "cosmic battery" concept is vital for launching rockets and understanding how planets stay in orbit. VHTC
- Tidal Forces - When gravity pulls unevenly across a body, tides happen! The Moon's gravity tugs harder on Earth's near side than its far side, creating ocean bulges we know as high and low tides. Wikipedia
- Gravitational Fields - Think of a gravitational field as an invisible map showing how strongly gravity will pull at any point. It's defined by g = G·M/r², pointing toward the mass that creates the field. Open Text BC
- Kepler's Laws of Planetary Motion - Kepler's three rules describe how planets race around the Sun: elliptical paths, equal areas in equal times, and a clear link between orbit size and period. These laws paved the way for Newton's gravitational insights. VHTC
- Gravitational Interactions in the Solar System - The Sun's gravity is the heavyweight champion, keeping planets in line, but planets like Jupiter throw in their own pulls, subtly shifting orbits and unleashing cosmic games of billiards. The Planets Today
- Gravitational Force Calculations - Plug masses and distance into Newton's formula to find the force between any two objects. For instance, two 1 kg masses separated by 1 m exert a tiny 6.674×10❻¹¹ N pull on each other. College Physics
