How to make a vehicle fly further away after a crash?

Hello guys,

i am currently working on vehicle vehicle crash physics, e.g. Car A hits Car B. Is there a variable (let’s call it “X”) or something else, that allows me to dynamically change the way (Force/Velocity) a vehicle flyes away after a hit/crash with another car? I want to be able to increase (depending on the other cars velocity) or decrease (using heal potion or smthn) the value of such a variable. Example:

Very low value of X and crash happens => Car doesnt really fly away.

High value of X and crash happens => Car flyes away a much longer distance

This variable shouldn’t change anything else of the car (like handling or acceIeration).

In other words and short: How can i increase the force impact to a vehicle after a hit?

i feel like you should be able to do something with the weight variable.
disclaimer: i have played very little with Force/Velocity within UE4.

If you mean the mass variable, i already tested that but this variable changes a lot of other stuff, e.g. acceleration. But thanks for the hint!
