Test your knowledge with a 30-question chapter practice test
Pulleys: Basic Mechanics

1. 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.

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 Done by a Variable Force

3. Work Done by a Variable Force

Doing work on an object is a simple concept: we apply a certain force over a certain distance. But in real life, that force is rarely constant. Therefore, we need to understand variable forces and be able to calculate them accurately.

Work-Energy Theorem: Definition and Application

4. 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.

Conservation of Mechanical Energy

5. 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

6. 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.
