Calculadora de Aceleração Angular

The Angular Acceleration Calculator determines the average angular acceleration (α) of a rotating body, calculated from the change in angular velocity (Δω) divided by the time interval (Δt). The formula used is α = Δω/Δt, where Δω is the difference between final and initial angular velocity, and Δt is the elapsed time. The result is expressed in radians per second squared (rad/s²).

This tool is useful for physics students, engineers, and professionals working with rotational systems such as motors, turbines, wheels, or any rotating object. For example, analyzing the acceleration of a fan when turning on or off, or the motion of a flywheel. It helps understand how rotational speed varies over time.

To use the calculator, input the initial and final angular velocities (in rad/s) and the time interval (in seconds). The tool automatically calculates the angular acceleration. Remember that angular acceleration can be positive (speed increase) or negative (deceleration). Ensure consistent units for accurate results.

Common precautions include verifying that angular velocities have consistent signs (same direction) and that the time interval is positive. For non-constant acceleration, the result is the average angular acceleration, not instantaneous. For uniformly accelerated rotational motion, this formula is exact.
