Its Value is represented as meters per second squared.

Example 1:

Javascript




// Move a touchscreen device to register
// Acceleration changes.
function setup()
{
  createCanvas(400,400)
}
  
function draw() {
  background(270);
    
  fill('red');
  textAlign(CENTER,CENTER);
  textSize(50);
  // Convert the acceleration into integer when
  // Device is moved along y-axis.
  text(int(accelerationY),windowWidth/2,windowHeight/2);
}


Output:

Example 2:
