How do I add Acceleration to Movement?

I'm new to scripting, so this might be too ambitious. The movement in Roblox is relatively simple, you press w, you let go of w, and you stop instantly.

Instead, I want to try and make a sort of acceleration mechanic. If I press w, and let go, it takes a split second to completely slow down.

Is there any way I can do this? Thanks, Pop.

Edit: Probably a better question would be, how would I add acceleration to Roblox movement?

This is something that you can do without even touching a script. If you insert a part into workspace, look at its properties, and change the friction to very low, the player will slide on it instead of coming to a dead stop. As for a script that could do this, it would be pretty challenging unless you can suddenly read all of roblox's scripts. Hope I helped!
