Description: May The F Equals Ma Be With You Funny

Description: Combine your love for science and geek culture with this funny "May the mass x acceleration be with you" design. Featuring Newton's second law, it is the perfect humorous graphic for physics nerds.

Description: A black background features a red apple with a green stem. To the left of the apple, the equation "F = ma" is written in white. Above the apple, white vertical lines indicate downward motion. To the right of the apple, a white downward arrow is next to the text "g = 9.8 m/s²". Below the apple, large white text reads "AND THAT REASON IS USU ALLY" followed by "PHYSICS" in green.

Description: May the f=ma be with you, because force = mass x acceleration. Perfect gift for geeky friends who can appreciate a good physics joke.

Description: The infamous Newton's second law in it's general form, that states that the variation of momentum in time is equal to the sum of forces applied.
