WebJan 31, 2024 · Negative angular velocity ( ω) means that the particle is revolving anticlockwise. Thus, negative angular acceleration ( α) is a "push" in the anticlockwise direction. If α and ω have the same sign, the body will speed up, else slow down (and eventually go in reverse). Actually, ω and α can be looked at as vectors as well. WebSay now we want to find the angular acceleration for a given angle θ, but not just for a very small amplitude. Even though we know that sometimes α is going to be negative and sometimes positive, it's always negative! …
