What does a negative angular acceleration indicate to you?
What does a negative angular acceleration indicate to you? 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). Is clockwise positive or […]
