Fast Jump/ Dash

I’m trying to get a movement system where I can jump really fast but not very high, much like rapid acceleration but also with very a abrupt deceleration , almost instant.

But I can’t get it to work properly, does anyone in here know a way of doing that?? Id really appreciate it.
I thought about using lerps but I don’t know how to pick were to lerp to whilst adding the current velocity…
Be aware that I’m not a really experienced programmer.

Thanks in advance for your help,

You could try something like this

GetComponent<Rigidbody>().AddForce(transform.up, ForceMode.Impulse);

and just tweak the values till it works for you.
