What is Buoyancy?
When gravity pushes on an active air plane, it creates _____.
What is weight?
Another word for Hydrodynamics.
What are fluid dynamics?
The buoyant force acting on a submerged object is equal to the weight of the fluid the object displaces.

A liquid decreasing in viscosity.
What will happen when a liquid gets heated?
An object that is neutrally buoyant.
What is an object that will neither float nor sink.
The relationship between lift and weight.
When water is pouring out a waterfall and crashes into rocks.
What is turbulent flow?
What is upward buoyant force?
A gas increases in viscosity.
What happens to a gas when it increases in temperature?
An object that has a stronger buoyant force than the gravitational force.
What is floating?
