This program covers the important topic of conservation of energy (part 2) in simple harmonic motion in Physics. We begin by discussing how in a perfect system energy is neither created nor destroyed. As the object swings, the energy is continually transferred from kinetic to potential forms and vice versa. The entire lesson is taught by working example problems beginning with the easier ones and gradually progressing to the harder problems. Emphasis is placed on giving students confidence in their skills by gradual repetition so that the skills learned in this section are committed to long term memory.
