Newton's Third Law: Newton's Third Law of Motion states that for every action, there is an equal and opposite reaction. This means the force of gravity exerted by the Earth on the car is exactly the same in magnitude as the force of gravity exerted by the car on the Earth.
But... The Earth is *much* more massive than a car. This means that the car's gravitational pull on the Earth is practically negligible. The Earth's enormous mass makes its gravitational pull dominant.
Here's the key point:
* The force of gravity is mutual: Both the car and the Earth exert a gravitational force on each other.
* The force is the same in magnitude: The Earth's pull on the car is equal to the car's pull on the Earth.
* The effect is different: The car's pull has a tiny effect on the Earth's motion due to its smaller mass, while the Earth's pull has a significant effect on the car's motion.
An Analogy: Imagine a tiny pebble and a huge boulder. Both exert a gravitational force on each other, but the boulder's pull on the pebble is much more noticeable.
In short: The car and the Earth experience the same force of gravity, but the Earth's immense mass means its gravitational pull on the car is far more significant than the car's pull on the Earth.
