Question

3 if john young removed his backpack on earth, it would fall to the ground, toward earths surface. this is the result of a force called gravity. based on this information, fill in the blank to complete the sentence. not all answer choices will be used. gravity can be described as a(n) blank between earth and an object. (options: barrier, direction, attraction, repulsion)

Explanation:

Gravity is the force that pulls objects toward each other. In the example, the backpack falls toward Earth's surface, showing that Earth and the backpack attract each other. "Barrier" is incorrect as gravity isn't a barrier. "Direction" is a property, not what gravity is. "Repulsion" is the opposite of attraction, so it's wrong. Thus, gravity is an attraction between Earth and an object.

Answer:

attraction
