Who's it for?
This chapter of our high school physics tutoring solution will benefit any student who is trying to learn about work, energy and power and earn better grades. This resource can help students including those who:
- Struggle with understanding variable force, kinetic energy to potential energy, the work-energy theorem, mechanical energy, pulleys, conservation of mechanical energy, the mathematics of power or any other work, energy and power topic
- Have limited time for studying
- Want a cost effective way to supplement their physics learning
- Prefer learning physics visually
- Find themselves failing or close to failing their work, energy and power in physics unit
- Cope with ADD or ADHD
- Want to get ahead in high school physics
- Don't have access to their physics teacher outside of class
Why it works:
- Engaging Tutors: We make learning about work, energy and power simple and fun.
- Cost Efficient: For less than 20% of the cost of a private tutor, you'll have unlimited access 24/7.
- Consistent High Quality: Unlike a live physics tutor, these video lessons are thoroughly reviewed.
- Convenient: Imagine a tutor as portable as your laptop, tablet or smartphone. Learn about work, energy and power on the go!
- Learn at Your Pace: You can pause and rewatch lessons as often as you'd like, until you master the material.
- Detail the characteristics of work.
- Explore work done by a variable force.
- Examine the importance of energy in nature.
- Distinguish between kinetic and potential energy.
- Discuss the applications of the work-energy theorem.
- Explain how mechanical energy can be applied.
- Describe the basic mechanics of pulleys.
- Understand the ways in which energy is conserved.
- Explore the mathematics of power.
1. 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.
2. 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.
3. 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.
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.
5. 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.
6. 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.
7. 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.
8. 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.
9. 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.
10. Intensity in Physics: Definition & Measurement
Intensity in physics is a fundamental concept that scientists and engineers often use. Learn what the definition of intensity is and how to measure it in this lesson.
