Primary resources
This link takes you to the Conservation of Energy section in the textbook.
This link provides analysis of a few examples for which energy is conserved.
A fun quirky thorough introduction to conservation of energy.
This next video shows how conservation of energy can be used to analyze the movements of a rollercoaster.
A rollercoaster is a perfect example of how useful Conservation of Energy can be.
This link is a thorough summary of conservation of energy and how it relates kinetic and potential energy.
Secondary Resources
A couple more examples of conservation of energy applied.
Similar to the rollercoaster, a person going down a slide can be analyzed using conservation of energy.
