Links for the Eighth Chapter

 

This video discusses potential and kinetic energy.

This video discusses the relationship between work and energy.

This video show how to use the potential energy equation and the kinetic energy equation.

This video shows how the First Law of Thermodynamics works for a very different system than what you are studying.

This video shows how to solve problems using the First Law of Thermodynamics.

This video shows how to add friction to the First Law of Thermodynamics problems.

This video shows how to add friction to the First Law of Thermodynamics in a different problem.

This video shows how the equation for the speed of a ball rolling down a ramp is derived. He goes on to do a hollow ball as well, but the first equation is the one we use, since the ball used in the experiments is solid.

This video shows you the difference between energy and power.

This video shows you two examples for calculating power.
