About This Chapter
NYSTCE Physics: Work, Energy & Power - Chapter Summary
Let us help you prepare for the New York State Teacher Certification Examination (NYSTCE) physics test with a review of the connections between work, energy and power. Watch the lesson videos to increase your understanding of:
- Work and variable force
- Kinetic, potential and mechanical energy
- Applications of the Work-energy Theorem
- Basic mechanical mechanisms
- Conservation of mechanical energy
- Power and its calculations
These engaging lesson videos are taught by expert instructors who are available to answer any questions you may have, and come with lesson worksheets and quizzes to help fortify your understanding of the physics connected to work. By completing the lesson quizzes, you'll know which topics need more review. Use the video tags linked to key parts of the lessons to go back over those sections and make sure you'll be ready on test day.
NYSTCE Physics: Work, Energy & Power - Chapter Objectives
The NYSTCE Physics test is a computer-based certification exam, made of 90 multiple-choice questions and one constructed-response item, and administered in a four hour and 15 minute testing session. Of the material presented in the exam 23% is on mechanics and thermodynamics, which may include questions related to the lessons provided here. Use the tools of this chapter, including the multiple-choice quizzes, to improve your understanding of the concepts of energy, work and power and practice your test-taking skills.
1. Overview of Work & Work by Variable Force
After completing this lesson, you will be able to explain what work is, and how to calculate work using the equation, and a force-distance graph. A short quiz will follow.
2. Energy: Definition & Types
After completing this lesson, you will be able to explain what energy is, list various types of energy, and identify which type or types of energy are present in a situation.
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.
4. 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.
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.
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.
