About This Chapter
Measurements in Physics - Chapter Summary
In these lessons, you'll learn about measurements in physics. Topics covered include calculations for gravity, an explanation of density, measuring atmospheric pressure, and more. After completing the chapter, you should be prepared to:
- Discuss the difference between matter, mass, and volume
- Explain how different objects can have the same mass, but different volumes
- Provide examples of high and low density
- Define specific gravity and understand how it is related to the density of an object
- Describe Archimedes' principle in relation to applied force
- Explain how barometric pressure is measured
Our subject-matter experts provide instruction on measurements in physics using plenty of examples so that the material is easily understood. The video timelines let you navigate the videos to focus on the topics you need to review. A brief multiple-choice quiz is available for each lesson to test your knowledge. You can also print the lesson quizzes and use them as worksheets.
1. Matter, Mass & Volume
After completing this lesson, you will be able to explain the difference between matter, mass and volume. You'll also be able to describe how two objects can have the same mass, but different volumes. A short quiz will follow.
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. Archimedes' Principle: Definition, Formula & Examples
Archimedes' principle deals with the forces applied to objects by the fluids around that object. This applied force reduces the net weight of any object in a fluid, whether it be a liquid or a gas.
4. Barometric Pressure, Measuring Atmospheric Pressure & Barometers
This lesson examines the causes of varying barometric pressure and how we measure them. After this lesson, you should better understand where barometric pressure values come from and why we care.
5. What is Specific Gravity? - Definition, Formula, Calculation & Examples
Why do some objects float while others sink? One of the factors that determines this is the density of the object. The density of an object is related to another important factor called specific gravity, which will be the main focus of this lesson.
