PPT-Energy Energy Energy is the power to do work. It is measured in kilojoules (kJ) and kilocalories

is essential for life and is required to fuel many different body processes growth and activities These include keeping the heart beating keeping the organs functioning maintenance of body temperature. kilojoules and YoukJ (kilojoules) is the measure of how much energy is in food and drinks. In order to maintain a healthy weight we need to balance our energy consumption and our energy output. Factor What are kilojoules (kj) or calories? Energy is measured in kilojoules (kj) or calories, so when we refer to 'energy in' we actually mean 'kilojoules in' (the kilojoules in the food we have eaten).
