Smooth transaction using move forward

Hello guys,

So i made a push (Knockback) using moving forward 40 pixels at 90 angle.

But what happens is the object that colides teleports the said 40 pixels in that angle, is there a way to make this transaction smoother?

The teleport is cool but i would like a more fluid effect :)

instead of 40 pixels use something like 100*dt (note that is DT in lower case) I learned this early on, increase the number or decrease that number based on how fast or slow you want to move.
