I have a car which uses vector force. I realized that when the force is large, the car will accelerate. But when the force goes below a certain number, the car will slow down (decelerate) due to friction / gravity / loss of momentum. How can I calculate the number between acceleration and deceleration? I want to set the vector force to that number so that the car will move at a constant speed without slowing down or speeding up. Thank you for your help!
