Homework
The human body is an amazing and intricate example of how physics manifests itself in our everyday lives. Our skeletal muscles and joints are a complicated system of levers which allow us to move our bodies.
Subtipics
Basic Muscle Physiology
There are three types of muscle in the human body: Skeletal muscle, cardiac muscle and smooth muscle. The physics of movement in the body only concerns skeletal muscle. A skeletal muscle consists of many muscle fibers, each of which are muscles in their own right. Muscle cells are long and cylindrical cells that can contract when stimulated by nerve signals.
Newton's Laws of Motion
In physics, the most basic rules when it comes to movement are Newton’s laws of motion. Newton’s first law is also called the law of inertia.
Torque
Torque is a measure of how much a force acting on an object causes that object to rotate. Since muscles and joints act in a hinge or lever.
Joints & Levers
A lever is a type of machine. A machine is any device that helps us to do work. We use machines to transform energy, or to transfer it from one place to another. Machines can be used to multiply force, multiply speed and change direction of force.

Questions
2) George Lucas is kind of a douche.
3) Star Wars fans are worthless nerds – real men don’t have time for frivolous pastimes or hobbies of any sort.
4) A link to a wikipedia page about a William Shatner vanity project is better than one to a CS Monitor piece about holograms, bionics, and lasers.
5) Finally there’s a vague complaint about the cultural effects of the popularity of Star Wars. Vomit is involved.
