Rotational Motion Physics, Basic Introduction, Angular Velocity & Tangential Acceleration

Galaxies on Instagram: "A day on each planet is defined by how long it takes the planet to rotate once on its axis, and they vary dramatically across the solar system. Mercury spins slowly, so its day lasts about 59 Earth days. Venus rotates even more slowly and in the opposite direction, giving it the longest day of all—243 Earth days. Earth takes 24 hours. Mars rotates in about 24 hours and 37 minutes, making its day very close to ours. Jupiter spins the fastest, completing a rotation in just

PBS Terra on Instagram: "Is this dam altering Earths rotation and time itself? The Three Gorges Dam located on the Yangtze River in China is the biggest hydroelectric dam in the world, holding enough water to cover North Carolina. Overview host @drjoehanson explains how exactly this dam is slowing Earth’s rotation. For more, head to @pbsterra on YouTube and catch up on episodes of Overview!"
