What is Energy? - Definition and Significance in Nature

1. What is Energy? - Definition and Significance in Nature

This lesson describes the nature of energy and how it is transferred from one source into another. Additionally, it will describe the significance of energy in natural systems.

Work: Definition, Characteristics, and Examples

2. Work: Definition, Characteristics, and Examples

Pushing a wall all day may feel like work, but unless you get that wall moving you're not doing any work according to the rules of physics. In this video lesson, you'll learn how work is defined as well as how to calculate the amount of work done on an object.

Work-Energy Theorem: Definition and Application

3. 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.

Kinetic Energy to Potential Energy: Relationship in Different Energy Types

4. Kinetic Energy to Potential Energy: Relationship in Different Energy Types

This video defines and describes kinetic and potential energy. You'll learn how different types of energy can be classified as potential and kinetic. You'll also find out how kinetic and potential energy are transformed.

What is Mechanical Energy? - Definition & Examples

5. What is Mechanical Energy? - Definition & Examples

In physics, energy is how work gets done. This video describes one important type of energy, mechanical energy, and provides examples of both kinetic and potential mechanical energy.

Linear Momentum: Definition, Equation, and Examples

6. 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.

Momentum and Impulse: Definition, Theorem and Examples

7. Momentum and Impulse: Definition, Theorem and Examples

To understand how a change in momentum affects an object, we look to impulse. In this lesson, you'll understand how impulse describes an object's change in momentum, as well as how changing the force or time of the impulse can have very different outcomes.

Conservation of Linear Momentum: Formula and Examples

8. 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.

What Are Simple Machines? - Definition, Types & Examples

9. 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.

Pulleys: Basic Mechanics

10. Pulleys: Basic Mechanics

Like other simple machines, pulleys can help us lift and move heavy loads with less effort. In this video lesson, you'll learn how pulleys do this as well as how this is possible while still obeying the law of conservation of energy.

Conservation of Mechanical Energy

11. 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.

Power: Definition and Mathematics

12. Power: Definition and Mathematics

Work involves moving an object with a force, but power tells us how quickly that work is done. In this lesson, you will learn about how power depends on both work and time as well as see examples of how to calculate power.
