1. Fluids in Physics: Definition and Characteristics
Fluids really know how to move! As flowing materials, fluids have some unique properties that help us understand and describe them. In this lesson you'll explore what fluids are and how they are defined in the world of physics.
2. Density: Definition, Formula & Practice Problems
In this lesson, you'll learn about density, the way in which density can be calculated from mass and volume, and that density of substances are constant. You'll get to calculate densities of various materials in different situations.
3. Buoyancy: Calculating Force and Density with Archimedes' Principle
Knowledge of the buoyant force is important when trying to understand why some objects float while other objects sink. In this lesson you'll learn about this unique force and how we apply it to various situations using Archimedes' Principle.
4. Practice Applying Buoyancy Formulas
In this lesson, you'll learn how to apply the buoyancy formula. You'll practice calculating the volume of different shapes and buoyant force and evaluate problems to determine if an object will float.
5. Pressure: Definition, Units, and Conversions
Have you ever wondered what pressure is and how it gets measured? In this lesson, we are going to define pressure and explain some of the units that are used to express measurements of pressure.
6. Hydrostatic Pressure: Definition, Equation, and Calculations
This video lesson will introduce you to hydrostatic pressure in a liquid, as well as provide examples for how to calculate the liquid's pressure at a given depth.
7. Applications of Pascal's Principle
After watching this lesson, you should be able to explain what Pascal's principle is, including providing the equation that represents it. You should also be able to provide examples of Pascal's principle in action and solve problems using the equation.
8. Fluid Mass, Flow Rate and the Continuity Equation
Fluids rarely stay put, so we need to understand how they move. In this lesson, you will learn about how the movement of fluids is influenced by the space it passes through, as well as see examples of how to calculate aspects of this movement.
9. Bernoulli's Principle: Definition and Examples
Understanding how a moving fluid's speed and pressure change as it flows along is not only important for building airplanes but also for backyard fun. In this video lesson you'll learn about Bernoulli's principle and identify some practical applications of this concept.
10. Bernoulli's Equation: Formula, Examples & Problems
Bernoulli's equation describes an important relationship between pressure, speed, and height of an ideal fluid. In this lesson you will learn Bernoulli's equation, as well as see through an example how in an ideal fluid, the dynamics of that fluid remain constant.
