How do I a dropped object fall linearly without C2 behavior?

I'm newbie in C2 and want to know how to make an object with dragdrop behavior fall linearly after dropped (by touch). Currently I associated platform behavior "fall through", but that way he makes a curvilinear motion before falling.

Thank you in advance the attention and collaboration of all.

On way to do this:

Add instance variable to the object (Fall) and make the value 0

Add events:

Object on DragDrop drop ---- object set Fall variable to 1

Object Fall variable = 1 ----- object set Y to Self.Y+3

On way to do this:

Thanks for the help, A0Nasser!

I tried it before, but it did not work the way I imagined.
