beanieb said:Well I know the inital velocity is zero (starting from rest) and the time is given. Converting 2 revs to rads is 12.57. So it completes 12.57 rads in 0.570s. I am also aware that ang accel = ang vel/time. I am just going around in circles trying to work it out. I was fairly sure it was wrong to assume speed is 22rad/s. (12.57/.570). Sorry if that's not enough but I am totally lost. First post so I wasnt sure what to put up
Angular acceleration is a measure of the rate at which an object's angular velocity changes over time. It is a vector quantity, meaning it has both magnitude and direction, and is typically measured in radians per second squared (rad/s²).
Angular acceleration refers to changes in an object's rotational motion, while linear acceleration refers to changes in an object's straight-line motion. Angular acceleration is measured in radians per second squared, while linear acceleration is typically measured in meters per second squared.
The factors that affect angular acceleration include the object's moment of inertia, the applied torque, and the distance from the axis of rotation at which the torque is applied. The direction of the applied torque also plays a role in determining the direction of the angular acceleration.
Angular acceleration can be calculated by dividing the change in angular velocity by the change in time. The formula for angular acceleration is α = Δω/Δt, where α is the angular acceleration, Δω is the change in angular velocity, and Δt is the change in time.
Angular acceleration is important in understanding rotational motion and how objects move and behave in space. It is also used in many real-world applications, such as designing vehicles and machines, and in understanding the motion of celestial bodies like planets and stars.
