I try to achieve a non linear movement with the Follow Path constraint.

I linked my object to a bezier circle using the Follow Path constraint. It follows the circle with a linear movement, meaning the speed of the object always stays the same.

I want to make the object move faster by time, by changing the curve of the evaluation time from linear to exponentially.

In short I want the movement of the object to get faster and faster. How can i achieve this?

The Evaluation Time property is keyframable, you can shape its F-curve to any function you like.

Select your bezier curve object, in the graph editor and expand it to show the Evaluation Time curve (add a keyframe if necessary if it doesn't show by default).

Under the Modifier panel add a Generator modifier, change poly order to $2$, and adjust the function to get the desired speed.

A possible way is to animate the "offset" of the constraint from 0 to some negative value:

    $\begingroup$ You can probably also add a generator to the offset property and make it exponential as well $\endgroup$
