3. Conservation of energy
Using the law of conservation of energy to see how potential energy is converted into kinetic energy
4. What are energy and work?
Here we learn what work and energy mean in physics and how they are related.
6. What is gravitational potential energy?
Learn what gravitational potential energy means and how to calculate it.
7. What is conservation of energy?
Learn what conservation of energy means, and how it can make solving problems easier.
9. Work as the transfer of energy
David explains "work" as the way forces transfer energy to and from objects
11. Work as area under curve
In this video David shows how the area under a Force vs. position graph equals the work done by the force and solves some sample problems.
12. Thermal energy from friction
In this video David shows how to find the energy generated by the force of friction and solves an example conservation of energy problem involving thermal energy.
14. Work/energy problem with friction
A conservation of energy problem where all of the energy is not conserved.
