Work-Energy Theorem: Definition and Application

1. Work-Energy Theorem: Definition and Application

Work and energy are closely related in physics. In this lesson, you'll learn what that relationship is as well as how we can apply it to various situations.

First Law of Thermodynamics: Law of Conservation of Energy

2. First Law of Thermodynamics: Law of Conservation of Energy

This video describes the first law of thermodynamics. Several examples of the application of this law are discussed. The significance of the law and its practical application are discussed as well.

Changes in Heat and Energy Diagrams

3. Changes in Heat and Energy Diagrams

Did you know that temperature and heat are not the same thing? Did you know that the temperature of water doesn't change when it boils? This lesson describes the relationship between heat and temperature. Diagrams are used to illustrate the relationship between heat and temperature during phase changes.

How to Calculate Specific Heat Capacity for Different Substances

4. How to Calculate Specific Heat Capacity for Different Substances

This lesson describes specific heat capacity and explains how the specific heat capacity of water helps to maintain a relatively constant temperature in nature. Learn how to identify the specific heat capacity of other common materials and how to calculate specific heat capacity with an experiment.

The Scientific Method: Steps, Terms & Examples

5. The Scientific Method: Steps, Terms & Examples

The scientific method is more than just hypotheses and experiments. In this lesson, we'll explore the themes and variations that make up the world of science.

Experimental Design in Science: Definition & Method

6. Experimental Design in Science: Definition & Method

What are the requirements of a scientific experiment? How do scientists turn hypotheses into theories and laws? Learn the answers to these questions and more in this lesson on the design of scientific experiments.

Significant Figures and Scientific Notation

7. Significant Figures and Scientific Notation

Are 7.5 grams and 7.50 grams the same? How do scientists represent very large and very small quantities? Find out the answers to these questions in this video.
