The formula used for finding the tangential speed (speed of something that is moving in a circular path) of an orbiting object is: V₍t₎ = ωr V₍t₎ = tangential speed or velocity ω = angular velocity r = radius of the circular path if time taken t is only given then use this formula to calculate the tangential speed: V₍t₎ = 2πr/t, t is time taken
liquid: A substance that flows and keeps no definite shape because its molecules are loosely packed and constantly moving. It takes the shape of its container but maintains constant volume.
