More on work and conservation of energy (8)

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.

he repeats things so much that you can't forget xD awesome!

thank u soooooooo much.....

but can u show the hole question to us>>> to know how it ganna be in the exaaaams???

thank u again man......

Your approach makes me understand fundamental ideas behind each formula. I've been learning physics, organic chemistry from you religiously. They have done a lot of good to me. Thanks.
