How tides work. Part One - Equilibrium theory

How do tides really work if the moon pulls on the whole Earth at once? To understand tidal forces, we first need to look at the equilibrium theory. This model strips the planet down to a water covered sphere and explains how the moon's gravity, weakening over distance, creates two tidal bulges on opposite sides of the Earth. We also bring in centrifugal forces from the Earth and moon orbiting their shared barycenter, spring and neap tides caused by the sun's alignment, and the reason why enclosed seas like the Mediterranean barely show any tides at all. By the end, you will have the foundation needed to tackle the more complex dynamic theory in part two. 0:00 Why tides are not as simple as they look 1:05 Building the equilibrium model 2:18 Gravity, inertia, and two tidal bulges 3:44 Spring tides, neap tides, and the sun 5:12 Why this model fails at real coastlines Related everWonder videos: Tides Part 2 - Dynamic Theory:    • How tides work. Part Two - Dynamic theory   Does the Earth Really Orbit the Sun:    • Does the earth really orbit the sun?   🌍 everWonder about the world?
