* Gravity: This pulls the car downwards towards the center of the Earth. This force is balanced by the normal force, which is the upward force exerted by the ground or surface the car is resting on.
* Friction: This force opposes any potential motion. It's present between the car's tires and the ground, and also within the car's mechanisms (like bearings in the wheels).
* Air Resistance: Even when not moving, there's still a small amount of air resistance acting on the car, although it's usually very minimal.
Important Note: The key thing to remember is that when a car is at rest, these forces are balanced. This means they are equal in magnitude and opposite in direction, resulting in a net force of zero, which is why the car stays still.
