LEARNING OBJECTIVESTODAY, I WILL
Observe how the potential energy, kinetic energy, and total energy of a pendulum change over time as a pendulum swings.
Identify the part of a pendulum swing in which potential energy is maximized and the part in which kinetic energy is maximized.
Interpret a graph of potential and kinetic energy.
Calculate the potential energy of a pendulum.
Calculate the kinetic energy and velocity of a pendulum based on its height change.
