Newton's second law of motion allows the prediction of an object's acceleration given its mass and the total force on it, \(a_{cm}=F_{total}/m\). This is only the one-dimensional version of the law; the full-three dimensional treatment will come in chapter 8, Vectors.
Cellulitis facts. 1  Cellulitis is a bacterial infection of the skin and tissues beneath the skin. 2  Staphylococcus and Streptococcus are the types of bacteria that are usually responsible for cellulitis, although many types of bacteria can cause the condition.
Infections. Infections can cause localized changes in skin color. Cuts and scrapes can develop infections that turn the surrounding skin red or white and change the texture of the skin. Erythrasma is a chronic skin infection caused by bacteria that causes pink skin with brownish flaky patches and wrinkling. Tinea versicolor and ringworm are infections caused by different types of fungi. These fungal infections can cause patches of skin to turn white, pink, tan, or brown and scaly. The patches can occur all over the body, depending on the exact type of fungus.
