More on work and conservation of energy (3)

Physics: Kinetic energy. Work and the work-energy theorem. Conservative and nonconservative forces. Gravitational potential energy; spring potential energy. Total mechanical energy. Net work by nonconservative forces = ΔE. Conservation of energy problems. A problem in which mechanical energy is not conserved.

Thank you for the lecture!

@wehpers23 well done ...keep up the good work

[wehpers23]

you are a dream come true.....thank you thank you thank you....you helped me get a B on my last test (and if you knew me and my physics skills you would know that is quite an accomplishment) :D
