5 ) Construct models that illustrate how energy is related to work performed on or by an object and explain how different forms of energy are transformed from one form to another (e.g., distinguishing between kinetic, potential, and other forms of energy such as thermal and sound; applying both the work-energy theorem and the law of conservation of energy to systems such as roller coasters, falling objects, and spring-mass systems; discussing the effect of frictional forces on energy conservation and how it affects the motion of an object).

We talk a lot about bridges in Physics. Why? Because there is a lot of practical physics that can be learned from the planning and construction of them. This video discusses simple harmonic motion, oscillation, resonance and how these relate to the problems with the Millennium Bridge.

When you hear the word, "work," what is the first thing you think of? Maybe sitting at a desk? Maybe plowing a field? Maybe working out? Work is a word that has a little bit of a different meaning in Physics. In this video, Dr. Shini is going to walk us through it. She will also discuss energy and power.
