Centrifugal force, an Uncommon card

The card carries these facts from its Wikipedia article.

• It appears to be directed perpendicularly from the axis of rotation of the frame.
• The magnitude of the centrifugal force F on an object of mass m at the perpendicular distance ρ from the axis of a rotating frame of reference with angular velocity ω is F = m ω 2 ρ {\textstyle F=m\omega ^{2}\rho }.
• The concept of centrifugal force simplifies the analysis of rotating devices by adopting a co-rotating frame of reference, such as in centrifuges, centrifugal pumps, centrifugal governors, and centrifugal clutches, and in centrifugal railways, planetary orbits and banked curves.

Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Centrifugal force article was read about 150,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 76 and blocks with 68: each hit it takes is cut by 27 %.

Open packs. Each pack holds five cards drawn from real Wikipedia articles, the rarest last, and the fifth card is always Rare or better. The odds are shown in the game. A free pack arrives every hour and two can wait, and the Coins you win in duels buy more packs.
