hey guys, im a little bit confused about how to calculate the acceleration of sideways friction for tracks.

ben used this code for calculating acceleration!

```
auto SlippageSpeed = FVector::DotProduct(GetRightVector(), GetComponentVelocity());
auto CorrectionForce = - SlippageSpeed / DataTime * GetRightVector();
```

what i really dont underestand is the way of Calculating CorrectionForce.

why we assign the minus(-) sign to the calculation process?

why even we multiple DataTime to a Vector?

i will be very thankful if someone explain these two questions.
