The same equations that describe a sliding block also describe a spinning wheel.
Mass m is replaced by moment of inertia I. Force F is replaced by torque τ. Velocity v is replaced by angular velocity ω.
Newton’s second law F = ma becomes τ = Iα. Momentum p = mv becomes angular momentum L = Iω. Kinetic energy ½mv² becomes ½Iω² and the work and power expressions follow identically.
Only the variables change. The structure stays the same.
It's My Birthday Month! Who shares the same month as me? (≧ω≦)/

Earth’s spin can hold a 100000 km cable taut once the system’s centre of mass sits at geostationary orbit.
The effective potential U(r) = −μ/r − ½ω²r² pulls inward below GEO and outward above it.
A counterweight beyond GEO keeps the tether in tension. Carbon nanotubes remain the leading candidate for the specific strength this taper requires. Climbers then ride the cable instead of rockets.
The rotation that flattens Earth can also hold a staircase into space.

Reggie's been gone a long time. Tonight his wife called a late night radio show to request a song for "someone who's working late."
Philly knew who was on line two. He didn't say who.
Last stop before the Season 4 finale.

Word has it that nodding off in class gets you some extra-special attention from the instructor! ₍₍ (ง ˙ω˙)ว ⁾⁾
