WebThe second is known as the 'double-impact theory', which states that a large celestial body hit Venus billions of years ago and created a moon, in a similar way to how Earth got its lunar companion. WebIn symbols, this is ω = Δ θ Δ t, 6.6 where an angular rotation Δ θ takes place in a time Δ t. The greater the rotation angle in a given amount of time, the greater the angular velocity. The units for angular velocity are radians per second (rad/s). Angular velocity ω is analogous to linear velocity v. small portable speakers for computer
