How to Use the Linear Acceleration Calculator

Using the Linear Acceleration Calculator involves the following steps:

  1. Enter Angular Acceleration (rad/s²): Input the angular acceleration of the rotating object in radians per second squared.
  2. Enter Radius (meters): Input the radius of the circular path along which the object moves.
  3. Calculate Linear Acceleration: Click the “Calculate” button to compute the linear acceleration.
  4. View Result: The calculated linear acceleration will be displayed, indicating the rate of change of the object’s linear speed.

The formula used by the calculator is AL=aa×rAL = aa \times rAL=aa×r, where ALALAL is the linear acceleration, aaaaaa is the angular acceleration, and rrr is the radius. This calculation helps predict how quickly the linear speed of a rotating object changes over time due to angular acceleration.
