The facts on the card
The card carries these facts from its Wikipedia article.
- A gravitational field is used to explain gravitational phenomena, such as the gravitational force field exerted on another massive body.
- It has dimension of acceleration and it is measured in units of newtons per kilogram or, equivalently, in meters per second squared.
- In its original concept, gravity was a force between point masses.
Why it is Uncommon
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Gravitational field article was read about 50,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 57 and blocks with 25: each hit it takes is cut by 10 %.
