Question

how is gravity defined?
a force that remains unexplained by scientific research
a force that attracts or pulls objects toward each other without direct contact
a force that repels or pushes objects away from each other

Explanation:

Gravity is a well - explained fundamental force in science. It is an attractive force, not a repulsive one. It acts between objects without them being in direct contact, pulling them towards each other (e.g., the Earth pulls objects towards its center, and celestial bodies attract each other). The first option is incorrect as gravity is explained by scientific theories (like Newton's law of gravitation and Einstein's general relativity). The third option is incorrect as gravity is attractive, not repulsive. So the correct description is the second option.

Answer:

B. A force that attracts or pulls objects toward each other without direct contact
