Eli5 Why is force equal to mass multiplied by acceleration and not speed ?

Question

If a car moves consistently at 80 kmh and it weighs at 600kg, is it not generating any force? since you know, a=0, am I stupid or is Newton ?

Answer 1

I think you are confusing force with momentum. If the car hit a wall there would be an impact force due to the momentum.
