What should I use to do this [Brick Smoothly Goes Down]?

I want to make a brick that when you jump on it, It goes downward in a smooth motion, and then when you jump off of it, It comes back up to where it started smoothly as well. I'm thinking I should use a Body[something, mabye Velocity] but I tried almost all of them and I couldn't seem to get it right. So what should I do?

Use a touch function to activate CFrame for the brick, then touch ended function to put it back into place

There are many ways to accomplish this, the best one out there in my opinion is using TweenService. It will give you a very smooth, fully customizable, motion!
