# Ch 13: Energy & Motion in Physics

Review your understanding of how to use calculations to find different types of energy and motion in physics. These lessons and quizzes can be used to build confidence on the topic before an exam or homework assignment.

## Energy & Motion in Physics - Chapter Summary

Our instructors explain the concept of work as it's defined in physics and how it relates to variable force. You will be introduced to Hooke's Law and how to use its equation. The concept of mechanical energy and how it is transferred and converted will be covered, along with gravitational potential energy and elastic potential energy.

As you work through the lessons, you'll review both inelastic and elastic collisions and how they relate to momentum. Tensive and compressive stress and strain, plus their related equations, will also be presented. You will learn how to calculate energy efficiency and define impulse. The law of conservation of momentum and the equation used to solve problems using it will also be introduced. After you have completed these lessons, you should be able to:

• Calculate work using an equation and a graph
• Solve problems using Hooke's Law
• Explain how mechanical energy is converted and transferred
• Differentiate between kinetic and potential energy
• Use the equations for gravitational potential energy and elastic potential energy
• Compare tensile stress and strain to compressive stress and strain
• Relate impulse and momentum
• Follow the equation for the conservation of momentum when solving problems

Our lessons and quizzes are designed by professional instructors, ensuring your study experience is easy and engaging. Before or after you've reviewed the lessons, take the quizzes to gauge your knowledge of the topic. If you have questions, contact one of our instructors for assistance. These mobile-friendly lessons and quizzes are available for you to review at any time, seven days a week.
