Answer:
- Without fluid friction, all objects accelerate at the gravity acceleration.
Explanation:
When an object moves through a fluid, like air, water or oil, the object experiences a resistance to flow; this is, to pass through the fluid.
This resistance force is the fluid friction.
In few words, fluid friction is a force that opposes the motion of the objects through the fluid.
Then, in the abscence of fluid friction, all objects falling accelerate at the gravity acceleration.
