The Laws of Thermodynamics

1. The Laws of Thermodynamics

Learn about the first and second laws of thermodynamics. Find out how energy is generated, how it converts from one form to another, and what happens to energy in a closed system.

Energy Conservation and Energy Efficiency: Examples and Differences

2. Energy Conservation and Energy Efficiency: Examples and Differences

Saving energy is an important topic, but energy conservation and energy efficiency are not the same thing. Learn what the difference is and some examples of both energy conservation and energy efficiency.

Conservation of Mechanical Energy

3. Conservation of Mechanical Energy

Energy comes in many forms and for any system can never be created or destroyed. This holds true for mechanical energy, which also obeys this law of conservation of energy. In this video lesson, you'll explore how mechanical energy is converted or transferred between forms and objects.

Linear Momentum: Definition, Equation, and Examples

4. Linear Momentum: Definition, Equation, and Examples

Any moving object has momentum, but how much momentum it has depends on its mass and velocity. In this lesson, you'll identify linear momentum, as well as see examples of how an object's momentum is affected by mass and velocity.

Conservation of Linear Momentum: Formula and Examples

5. Conservation of Linear Momentum: Formula and Examples

The law of conservation of momentum tells us that the amount of momentum for a system doesn't change. In this lesson, we'll explore how that can be true even when the momenta of the individual components does change.

Conservation of Angular Momentum

6. Conservation of Angular Momentum

After watching this video you will be able to explain what is meant by conservation of angular momentum. You will also be able to use this concept along with the equation to solve problems. A short quiz will follow.

Simple Harmonic Motion (SHM): Definition, Formulas & Examples

7. Simple Harmonic Motion (SHM): Definition, Formulas & Examples

After watching this video, you should be able to explain what simple harmonic motion is, describe the features of the motion, and use equations to solve simple harmonic motion problems, particularly for a mass on a spring. A short quiz will follow.

Hooke's Law & the Spring Constant: Definition & Equation

8. Hooke's Law & the Spring Constant: Definition & Equation

After watching this video, you will be able to explain what Hooke's Law is and use the equation for Hooke's Law to solve problems. A short quiz will follow.

Spring-Block Oscillator: Vertical Motion, Frequency & Mass

9. Spring-Block Oscillator: Vertical Motion, Frequency & Mass

After watching this video, you will be able to explain how a spring-block oscillator is an example of simple harmonic motion. You will also be able to use an equation for a spring-block oscillator that relates the frequency and mass of the block.

What is Temperature? - Definition & Measurement

10. What is Temperature? - Definition & Measurement

In the most intuitive terms, temperature refers to how hot or cold something is. Learn more about temperature as a measure of the average kinetic energy of the particles in an object and test your knowledge with quiz questions.

What is Heat? - Definition & Explanation

11. What is Heat? - Definition & Explanation

In this lesson, you will learn the definition of heat and find out how it differs from temperature. You will also explore practical applications of heat such as expansion, thermodynamics, heat transfer, specific heat, phase transitions, and heat engines.

Mechanisms of Heat Transfer: Conduction, Convection & Radiation

12. Mechanisms of Heat Transfer: Conduction, Convection & Radiation

There are three main ways that heat is transferred between substances or objects. In this video lesson you'll learn about each one, and identify the differences between them.

Changes in Heat and Energy Diagrams

13. 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

14. 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.

Calorimetry: Measuring Heat Transfer and Heat Capacity

15. Calorimetry: Measuring Heat Transfer and Heat Capacity

This video lesson explains the technique of calorimetry used to measure heat transfer in chemical reactions. You will see how different materials have different specific heat capacities. You will learn how to carry out heat calculations using a simple equation.

The Relationship Between Enthalpy (H), Free Energy (G) and Entropy (S)

16. The Relationship Between Enthalpy (H), Free Energy (G) and Entropy (S)

In this video lesson, we'll study free energy (G) and its relationship to enthalpy, entropy and temperature. You'll also learn why free energy (G) is the single most useful criterion for predicting the spontaneity and direction of a chemical reaction.

Predicting the Entropy of Physical and Chemical Changes

17. Predicting the Entropy of Physical and Chemical Changes

Ever wonder why your bedroom always ends up a mess within hours of you tidying up? That is the magic of entropy. In this lesson, you'll learn why disorder is the natural state of matter and how we can predict entropy change in a physical or chemical reaction.
