Physics is all around us. From astral bodies, to apples or other objects falling, to the energy transfer from the sun and finally to the machines humans created to help them in everyday life. Since Nature has everything perfected through evolution, humans use it as a source of inspiration for engineering new tools, machines and materials. Physics is involved in all stages of the process: from understanding how things work, to developing new machines and then assess their function.
This unit focused on understanding levers in the human body. An extension of the unit would be to focus on methods used in biomedical engineering in helping repair these body parts when needed (prosthetic limbs for amputees, bone implants etc).
