Some ordinary and everyday physics phenomena are counterintuitive when first encountered. Examples:

  1. demo of moment of inertia of cylinders rolling down an inclined plane by prof Walter Lewin: https://youtu.be/cB8GNQuyMPc

  2. better aerodynamic design for spaceship re-entering the atmosphere : https://youtu.be/v1_WqVguRJg (start watching from 43:23)

  3. leaning tower of Pisa experiment by Galileo Galilei to prove that heavier and lighter objects take same time to fall from a given height

  • $\begingroup$ Kapitza's pendulum is pretty strange (en.wikipedia.org/wiki/Kapitza%27s_pendulum), a double-hinged pendulum which can be in dynamic equilibrium pointing up. $\endgroup$ – Cryo Apr 4 at 22:22
  • $\begingroup$ Thanks Cryo...I wasn't aware of something like kapitza's pendulum. Reminded of watt governor $\endgroup$ – user221238 Apr 6 at 3:05
