animating scale with acceleration and weight

[nemsi]

Hi guys,

i would like to animate an object rotating 360° with some acceleration and slow down with weight..

Is there some fonctions or better to do all by hand.

Thank you

Animate it by hand.

there are three basic types of expression based animation between two frame values, mix and match as you like:
 

//linear:
float tx = fit($FF,1,10,2,21);
//exponential:
float tx = fit01(pow(fit($FF,1,10,0,1),3),2,21);
//smooth:
tx = fit01(lerp(1,10,$FF),2,21);
