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

Energy is the capacity or ability to perform work, which is significant in causing anything to move within nature. Explore the different types of energy, where it comes from, why it is necessary, and how it is important in natural systems.

### 2. Work: Definition, Characteristics, and Examples

In physics, work refers to the distance an object moves due to the force applied to it. Learn about the definition, components, and characteristics of work, and discover how to calculate the amount of work done on an object through some examples.

### 3. Work Done by a Variable Force

In physics, work is simply the amount of force needed to move an object a certain distance. In this lesson, discover how to calculate work when it is done by a variable force using rectangular approximation and integration.

### 4. Work-Energy Theorem: Definition and Application

The work-energy theorem relates the net work done of forces on an object and the change in the kinetic energy of the object. Learn about the definition and application of the work-energy theorem, explore work as a change in energy, discover how the work-energy theorem can be applied to the potential energy of an object, and understand how the increase or decrease in energy is associated with the work-energy theorem.

### 5. Kinetic Energy to Potential Energy: Relationship in Different Energy Types

Kinetic energy and potential energy are created differently. In this lesson, we will dive into different types of energy, and how they can be transformed into other types of energy.

### 6. Gravitational Potential Energy: Definition, Formula & Examples

Gravitational potential energy (GPE) is a type of potential energy which is generated using height and the presence of gravity. Learn why GPE exists, explore the formula to calculate the energy precisely, and look at examples of how 'what goes up must come down' is described through GPE.

### 7. Elastic Potential Energy: Definition, Formula & Examples

When an object can be deformed and return to its original shape, it has elastic potential energy. Discover what elastic potential energy is, learn how to find it using Hooke's Law, and use the formula to work through examples.

### 8. Conservative Forces: Examples & Effects

Energy is conserved when the forces acting on an object are only conservative forces. Learn about conservative force and its effects on the conservation of energy, and see examples of conservative forces such as force due to gravity and elastic spring force.

### 9. Nonconservative Forces: Examples & Effects

Nonconservative forces do not conserve energy within a system or that allow energy to dissipate from it. Learn how path dependence can reveal a nonconservative force, and also about the most common type of nonconservative forces, which are frictional forces, such as static friction, for example.

### 10. Conservation of Mechanical Energy

In physics, mechanical energy refers to the power that an object obtains based on its position or movement. Learn about the conservation of mechanical energy, including kinetic and potential mechanical energy. Explore how energy is conserved in a system, review conservation in action, and recognize outside forces on the system.

### 11. Power: Definition and Mathematics

Power in mathematics refers to how much work can be done in a certain amount of time, meaning the more work that can be done in the same amount of time means more power. Study the definition of power in mathematics and how it is calculated.
