Design a Better Vortex Cannon - Science Friday
WEBMar 24, 2016 · An air vortex cannon works primarily by applying force quickly and efficiently to air molecules contained in a semi-enclosed space. When the stretchy balloon surface at the back of the cannon snaps forward, it collides directly with air molecules, accelerating them towards the opening of the cannon and setting off a chain reaction of high-speed collisions with other air molecules and the sides ...
Gravity And Centripetal Force In Our Solar System - Science Friday

The inertia from the creation of the planets sent them flying in a straight line, perpendicular to the force of the Sun’s gravity. When these forces combine, they result in centripetal forces that push our planets in their circular motion around the Sun.
