Energy and Work
Matter and energy make up the universe. Energy is the mover of mass. Energy is abstract and is best viewed as it changes form.


Potential Energy
What happens to the potential energy of an object if you double its height? How much potential energy does an object have if its mass is 2 kg and it is raised to a height of 3 meters? 

Kinetic Energy
Kinetic Energy is energy of motion.


Thermal Energy
WorkEnergy Theorem


Conservation of Energy
(also called the 1st law of thermodynamics) In a closed system the total amount of energy,including heat, is conserved. In other words, although the kind of energy in a given system can change, the total amount cannot. Energy is converted from one form to another and is not lost.
Energy exchanges drive all interactions

Inclined Plane,Wedge and Screw
A machine is a tool that makes work easier. Machines accomplish this by exchanging force and distance.
