About This Chapter
Understanding Force & Pressure - Chapter Summary
Learn more about force and pressure as you complete this chapter. Our expert instructors will walk you through the definitions and calculations involved with these concepts. You can use these lessons to study:
- Facts about pressure and hydrostatic pressure
- Uses for fluid mass, flow rate and the continuity equation
- Examples of simple machines
- Equations related to torque
In addition to providing you with information about how force and pressure can be applied, these lessons work to familiarize you with vocabulary words. You can test what you're learning with the quizzes at the end of every lesson. If you find you need to study a specific subject further, the quizzes include links back to the lessons.
1. 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.
2. 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.
3. 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.
4. What Are Simple Machines? - Definition, Types & Examples
If you need to move or lift a heavy object, it would be wise to use a simple machine. Though these devices are far from fancy or high-tech, they are extremely helpful for getting work done.
5. What is Torque? - Definition, Equation & Calculation
You've probably heard of torque before, maybe while discussing cars. Now learn what it really is, and what it has to do with rotational equilibrium. Then, work through an example problem that combines the two.
