* Gravitational Force: The force of gravity between two objects depends on their masses and the distance between them. The greater the mass, the stronger the gravitational force.

* Comparing Objects:

* A car has a significantly larger mass than a book, house, or human being.

* While a house is large, it's primarily made of relatively lightweight materials.

Therefore, the car, with its greater mass, will exert the strongest gravitational pull on the Earth at its surface.
