To draw: Simple sketches showing a person stretching a spring.
Introduction: Energy is necessary for all living organisms to perform their life processes. Living cells obtain energy in a different form and they also have the mechanisms to alter energy from one form to another form. Energy is defined as the capability to do work.

Introduction: Energy is necessary for all living organisms to perform their life processes. Living cells obtain energy in a different form and they also have the mechanisms to alter energy from one form to another form. Energy is defined as the capability to do work. When the work is done, energy is transferred from one form to another form or between systems. Energy is generally expressed in units of work that is kilojoules (kJ). Energy can also be expressed in units of heat energy, that is, kilocalories (kcal).

To draw: Simple sketches showing the release of tension.
