What is Reaction Force at Vehicle?

The reaction force at a vehicle is the force exerted by a surface or contact point in response to the vehicle's weight or any applied forces. For instance, when a vehicle rests on the ground, the reaction force from the ground opposes the vehicle's weight, preventing it from sinking. Similarly, during braking, the reaction force from the tires on the road helps decelerate the vehicle. This force is crucial for maintaining stability and balance in various driving conditions.
