Work is the the amount of effort that is spent when a force causes an object to move a distance. For example, when you are carrying your books and binder to the next class work is being done because a force is acting on your books and binder to hold them up while you carry them a distance to your next class. When you are waiting outside of the classroom door no work is being done even though a force is still acting on your books and binder to hold them up, no distance is being traveled so no work is being done.
Eureka Video on the Inclined Plane/ Work and Energy:
Work is measured in joules, forces are measured in Newtons, and distance is usually measured in meters. Work (W) is calculated by multiplying the the force (F) applied to the object by the distance (d) the object traveled. Therefore the equation used to calculate work is W=Fxd or W=Fd. By re-arranging the formula, you can also find missing numbers. To calculate force: F= W/d
To calculate distance: d=W/F

What is energy?(pg 107 textbook) Energy is the ability to do work. The metric unit for energy is the joule (J).
Energy (pg 108 textbook) Energy can come in many forms such as thermal or elastic but all forms can be classified into the two categories of kinetic and potential energy. Kinetic energy is the energy of an object in motion for example a toboggan going down a hill has kinetic energy (e.g. electricity, thermal, energy, and sound). Potential energy is the opposite of kinetic energy, potential energy is stored energy.We can do work because of potential energy found in the food that we eat. A type of potential energy is called gravitational potential energy. This is potential energy that is stored in an object that is able to fall (e.g. an apple held in your hand) Although the two forms of energy are completely different they are both very important.
