Here's the breakdown:
* Gravity is a mutual force: Gravity is a force of attraction between any two objects with mass. The Earth exerts a gravitational force on the car, pulling it down. But, the car *also* exerts a gravitational force on the Earth, pulling it upwards.
* Equal and Opposite Forces: Newton's Third Law tells us that these forces are equal in magnitude and opposite in direction. This means the force the car exerts on the Earth is *exactly* the same as the force the Earth exerts on the car.
* Different Effects: While the forces are the same, the effects are very different. The Earth is immensely massive compared to a car. Therefore, the car's pull on the Earth is negligible and doesn't cause any noticeable motion. The Earth's pull on the car, however, is what keeps the car on the ground.
In summary:
* The force of gravity the car exerts on the Earth is equal to the force of gravity the Earth exerts on the car.
* The effects of these forces are vastly different due to the difference in mass between the car and the Earth.
