Answer
In this situation, the force NOT acting on the car object is 'Lift.'
Explanation
First of all, let's breakdown the kind of forces affecting a moving car:Normal Force: This is the force exerted by the ground (or any other surface in contact) on the object perpendicular to the surface. In our case, when the car is on road, the ground exerts this force, so it is certainly acting on the car.Driving Force: Also known as the propelling force, this is delivered by the engine, which propels our car forward or backward according to our steering controls. Therefore, it is also acting on the car. Weight: This is a force exerted by the mass due to gravity. As our car is present on Earth, the car's mass makes it experience gravity; effectively, it experiences weight. So, the force of weight haunts every object that has mass, including our car. Lift: This is an upward force that opposes the weight of an object and holds it in the air. However, our car in the present case, assuming that it's a normal car and not an aircraft or a flying car, does not experience 'Lift.' 'Lift' is primarily reserved mainly for airplanes and birds, where providing an upward force is a physiognomy requirement.
