Some questions about app development

Is it possible to have a variable that is the g-forces acting on the car. Is this right?

Code:

MyAppsName.prototype.update = function(streams){
    //convert to G
    var gForces = {};
    $.each(streams.sensors, function(index, val) {
        gForces[index] = val / 9.81;
    });

and would the variable be: gForces


The second question is how is it possible if that variable is greater than, say, 1 it will print out "Crashed"? Is this right?

Code:

if ('gForces' > 1) {
    $("<h1>Crashed</h1>").appendTo(this.rootElement);
}

and have it stay like that until the car is reset. I have a thing earlier in the app that will say "Alive" can I make it loop back to the begging once the car is reset.


Sorry if this is in the wrong section, I wasn't really sure where to put it
