... How is Energy Related to Work? • Energy is defined as the ability to do work. Recall that work is the product of force and distance. If a force acts through a greater distance, it has done more work. You can use work to measure changes in energy. • Place two identical books on the table so there is ...

... There are two TYPES of energy: potential and kinetic. Energy can’t be created or destroyed so we need to convert energy we have into what we need. The energy we use comes from many sources: Fossil fuel (coal, oil, natural gas), nuclear power, sun, wind, geothermal, hydropower. Most of this we conver ...
