Course content

4 sections • 24 lectures • 2h 14m total length

1 - Introduction to Fluid Statics1:59
This opening lesson introduces the fluid statics unit and sets up the main ideas students will use throughout the course: density, pressure, buoyancy, and organized problem solving.

2 - Fluid Physics - States of Matter8:08
An overview of the states of matter—solids, liquids, gases, and plasmas—and how their molecular structure governs flow, compressibility, and volume in fluids.
3 - Fluid Physics - Density7:37
4 - Fluid Physics - Specific Gravity3:34
5 - Fluid Physics - Density and Temperature7:25
6 - Fluid Physics - Density Example Problems8:57
7 - Fluid Physics - Specific Gravity Example Problems2:32
Explore specific gravity as a density ratio to water and predict sinking or floating, with example problems using densities in kg/m^3 for copper, aluminum, balsa, oak, and mercury.

8 - Fluid Physics - Pressure5:40
9 - Fluid Physics - Pressure Example Problem3:49
10 - Fluid Physics - Pressure in Fluids3:37
11 - Fluid Physics - Pressure with Depth5:40
12 - Fluid Physics - Pressure Example Problems6:34
The lecture explains how to compute pressure at depth in freshwater and seawater, showing how density and depth raise pressure in pascals, and how area affects pressure.
13 - Fluid Physics - Atmospheric and Gauge Pressure5:34
14 - Fluid Physics - Gauges4:50
Explore gauges for measuring pressure, focusing on the mercury barometer and open manometer. Learn how atmospheric pressure and both gauge pressure and absolute pressure are inferred from fluid height differences.
15 - Fluid Physics - Pascal's Principle2:39
Pascal's principle states that external pressure applied to a confined fluid raises pressure at every point, as seen in a toothpaste tube, an inflated balloon, and hydraulic brakes.
16 - Fluid Physics - Pascal's Principle Example Problem3:12
17 - Atmospheric Pressure and Gauge Pressure Example Problems14:09

18 - Fluid Physics - Buoyancy and Archimedes' Principle4:59
This lecture explains buoyancy through Archimedes' principle, showing how pressure increases with depth, creating an upward buoyant force from the top and bottom surface differences.
19 - Fluid Physics - Applying Newton's 2nd to Buoyancy5:16
20 - Fluid Physics - Buoyancy Quantified4:52
21 - Fluid Physics - Archimedes Principle2:36
22 - Fluid Physics - Buoyancy, Density, and Specific Gravity7:32
23 - Buoyancy and Archimedes Principle Example Problems11:19
Demonstrate buoyancy and Archimedes principle with solved examples: compare buoyant forces on submerged objects of equal volume, apply density and specific gravity, and analyze floating and tension scenarios.

Description

This course is one of several Mousseau Physics courses designed for students in high school physics, AP Physics, and introductory college physics. In this course we focus on fluid statics, which is the physics of fluids at rest. Students will study density, pressure, gauge pressure, absolute pressure, pressure variation with depth, Pascal's principle, hydraulic systems, buoyant force, and Archimedes' principle.

The videos and resources include clear lectures, demonstrations, simulations, and worked out example problems. Students will practice choosing the right model, organizing known values, using units carefully, and connecting equations to physical situations involving liquids, gases, floating objects, submerged objects, and pressure changes. The course emphasizes both conceptual understanding and algebra based problem solving.

This course is a strong fit for high school physics students, AP Physics students, and introductory college physics students working through fluids. It does not require calculus. Students who have seen pressure and buoyancy before but still feel unsure can use the course to slow down, rebuild the core ideas, and practice problems step by step.

By the end of the course, students should be more comfortable explaining why pressure changes with depth, how hydraulic systems multiply force, why objects float or sink, and how to solve fluid statics problems in a structured way. It also provides a useful foundation for fluid dynamics, where the course shifts from fluids at rest to fluids in motion.

Students can work straight through the course as a full unit or use individual lessons as targeted support alongside a class. The videos are built to be paused, rewound, and practiced with pencil and paper, so the course works well for homework help, test review, exam preparation, or rebuilding a topic that did not fully click the first time.
