Today in class we worked with GPE <--> KE conversions and the formula for Kinetic Energy (KE = 1/2mv^2)
We worked some sample problems solving for height of a vertically launched projectile using the KE it had at the start, and some for finding velocity of a dropped item if given its original mass and GPE.
Next week we'll work with some real-world applications of energy - my favorite is with car crashes, but some others as well; Energy is far reaching in this course.
