Work

• Describe and mathematically calculate the specific changes in energy involved when a system undergoes a physical change due to work done by external forces.

• Apply the mathematical relationship between work done, the applied force, and the distance moved along the exact line of action of the force.

• Describe the fundamental energy transfers occurring when physical work is done on an object.

• Understand that a force definitively does work on an object only when that force causes a physical displacement of the object.

• Recall and correctly apply the equation:

$W = F s$
