Before, only the change in kinetic energy was there. If that work is on the energy side, I should call it some type of energy. I will call it gravitational potential energy: !

Test your knowledge of kinetic energy and gravitational potential energy, elastic potential energy and work done with this ten-question physics quiz.

The Work Energy Principle is one of the big ideas in introductory physics courses. It’s so big that the textbook presentation can get a little confusing – but it doesn’t have to be that way ...

For an example of gravitational potential energy, consider a book placed on top of a table. To raise the book from the floor to the table, work must be done, and energy supplied.

In National 5 Physics investigate the conservation of energy law; examine how gravitational potential and kinetic energy relate when items fall from height.
