A sample from this course

One topic, as StudyPath teaches it.

Measuring and converting energy: force, work, energy, power. Forms of energy. Heat,

This topic teaches how to define and relate force, work, energy, power and heat, and how to measure and convert them using correct units. For examinations, you must be able to distinguish the ideas clearly, use the key formulas correctly, and recognise different forms of energy and how one form changes into another.
