A fluid’s motion is affected by its speed, density, and viscosity, and weight, as wells as drag and lift. Use an example of a pipe with different sized openings on either end to observe and quantify laminar flow of liquids. Learn about the concept of flux, and how it is used to calculate the power of a system with moving fluid.

What is elastic potential energy? (article) | Khan Academy
The energy density of a coiled steel spring is about 8 kJ/kg, whereas a lithium-ion battery has an energy density of around 500 kJ/kg [1]. How can we calculate elastic potential energy for an ideal spring?
