In the past few weeks of physics, we have learned about how static electricity works.  When an object becomes negatively charged (gains electrons), it tries to become neutral, through losing electrons.  To do so, many objects give electrons to water molecules in the air, due to these molecules being polar.  In a humid environment, the air is filled with water molecules.  This causes a person to have an easier time having a neutral charge again.  However, in a dry environment, like a ski resort, there is a smaller amount of water molecules in the air.  This makes it difficult for a person, like me, who gains a charge, to lose the excess electrons.  After the picture below was taken, I took off my beanie and felt my hair start to stand up.  It was really WEIRD

The past few weeks, we have learned about torque.  I learned that, as seen in the picture below, I am able to balance the object due to their being no net torque.  If there were a net torque, this would cause rotation, forcing the object to fall off of my shoulder.  However, due to the torque ccw and torque cw being equal, the object has no rotation, allowing it to remain on my shoulder.  We learned that torque is eqaul to (forceXlever arm length).  In the picture, the torques are equal because their distance to the lever arm (my shoulder) is equal.  The force is also equal because both sides have equal weights.  Torque was a very fun concept to learn about.
