When an object falls through the air, it experiences air resistance which increases with speed. Eventually, the object reaches a point where the air resistance equals the __________ and no longer accelerates.
Find the correct option-
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → Gravitational force
A falling body is pulled down by its weight, the gravitational force, and pushed up by air resistance, which grows as the speed grows.
When the upward air resistance becomes equal to the gravitational force, the net force is zero, the acceleration stops and the body continues at a steady terminal velocity.
