Summary

The basic concepts of energy science—work, force, energy and power—and their relationships are explored in this unit. Students investigate the physical properties of energy through work and power and perform energy-related calculations and unit conversions. A hands-on model waterwheel activity engages students in learning how to calculate the amount of power produced and work done.

Engineering Connection

The fundamental physics concepts of work, force, energy and power are applied in many fields of engineering. Devices that mechanical engineers design to move, lift, push, and pull require energy to function, such as construction and agricultural equipment, elevators and escalators, and airplanes and rockets. An engineer must know how to calculate the power and energy needed to do the necessary work or provide the required heat.
