Who's it for?
This chapter of our high school physics tutoring solution will benefit any student who is trying to learn about fluid mechanics and earn better grades. This resource can help students including those who:
- Struggle with understanding fluids, density, pressure, buoyancy, fluid mass, Bernoulli's Principle, Toricelli's Theorem or any other fluid mechanics topic
- Have limited time for studying
- Want a cost effective way to supplement their physics learning
- Prefer learning physics visually
- Find themselves failing or close to failing their fluid mechanics in physics unit
- Cope with ADD or ADHD
- Want to get ahead in high school physics
- Don't have access to their physics teacher outside of class
Why it works:
- Engaging Tutors: We make learning about fluid mechanics simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live physics tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about fluid mechanics on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Explore the characteristics of fluids in physics.
- Define density and pressure.
- Explain the correlation between hydrostatic pressure, area and force.
- Discover the importance of buoyancy and the buoyant force.
- Learn about fluid mass and flow rate.
- Define and provide examples of Bernoulli's principle and equation.
- Understand Torricelli's Theorem.
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. What Is Density? - Explanation & Examples
After watching this video, you will be able to explain what density is, give examples of high and low density, and calculate density using an equation. A short quiz will follow.
3. 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.
4. 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.
5. 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.
6. 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.
7. 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.
8. 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.
9. Torricelli's Theorem: Tank Experiment, Formula and Examples
Torricelli's theorem has practical applications in everyday life. This physical law explains an important relationship between fluid exit velocity and the height of that fluid in a container. Here, you will learn about this relationship as well as see how to calculate exit velocity using Torricelli's theorem.
10. Flow Rate: Definition & Equation
In this lesson, you'll learn how to quantify the amount of fluid flowing through a pipe, channel, or other container. We will see that it depends on both the dimensions of the container and the speed of the fluid.
