Kinetic EnergyCurrent Lecture- Guest Lectureo Cellular functions controlled by binding reactionso Molecular contributions to condensationo HeLa Cell Line Genes from human carcinomao C. elegans o Nucleosome packing- Energyo Scientific vs. colloquial usageo Physics, Chemistry, and Biology- Kinetic Energyo Energy of motiono What factors affect it?o Denoted at Ko Equal Speed The larger the mass, the larger the K.o Equal Masses The larger the velocity, the larger the K.o Scalar quantity Direction doesn’t matter You don’t “eat calories to the right”o Kinetic Energy and Speed Displacement Force is proportional to speed is proportional to displacement is proportional to K. Velocity vs. Time GraphThese notes represent a detailed interpretation of the professor’s lecture. GradeBuddy is best used as a supplement to your own notes, not as a substitute.- Derivative = acceleration- Integration = area- Worko If a force is applied to a object, the work done by that force is defined as the dot (scalar) product of the force and the displacement of the point of application of that force.oW =F⋅d x=|F||d x|cos
