I need to slowly stop my object when he hits another object.

So I have a rocket and I need to stop it slowly when it overlaping another object. I tried to do - " Every tick rocket.speed-1 " but as you may guess Its not working.

Increase deceleration when overlapping?

or

every tick: rocket is overlapping X -> set rocket speed = lerp(rocket.speed, 0, x)

where the closer x is to 1 the faster it will slow down.

Thanks) already did it with - every tick / rocket.car.speed-10
