What it is
- This video defines work, energy, and power and describes how these concepts are related.
- Students will learn about the equations for work, kinetic energy, gravitational potential energy, spring potential energy, and average power.
- The video also explains what a system is and compares non-conservative and conservative systems, specifically highlighting the example of a simple pendulum.
Teaching tips
Positives
- The video animations demonstrate key concepts and display important equations and definitions.
- Students can see how mathematical concepts in trigonometry and calculus relate to physics and the real world.
Additional Prerequisites
- Students should already be familiar with forces including applied, gravitational, frictional, and spring forces.
- The last 30 seconds of the video are credits and sponsors.
- Many high school students will not be familiar with the calculus concept of integrals, which is mentioned in the video.
Differentiation
- This video can be used in math classes to apply vectors or trigonometry functions to real-world calculations.
- Understanding the basics of work, energy, and power is an important precursor to learning about energy sources, which is a key issue in climate change.
- Students can discuss Earth as a system and how climate change is impacting the energy flow in this system.
From the scientist review
The video simplifies the concept of power, energy, and work and provides a basic illustration of how energy works in a system. There is a high confidence to use this resource for teaching.
