Today we were working on a packet entitled "Lesson 4: Raising the Bar". In this packet, it contained bar graphs dealing with real life problems, with money. "We can use charts to represent data by showing things happening over time, comparing, and contrasting.
But the idea is that the 'money' is doing work. There is an initial state, and a final state. For example, look at the graph at the top.
It show that there is a change in the initial and final. Compare this to being work; there can be positive or negative work. If the amount of money you're spending/taking away, that would be the 'negative work'. If the amount of money you're earning, that would be the 'positive work'. By showing the initial and final states, you put the before chart next to the after chart.
Now, think about how this is like doing work. Leave a comment if you want on how I can improve or what not, thans :]

You show the work on a system in the middle section of the bar graph, right? I just want to make sure.

Yea but you only show it when energy was added or taken away not when the energy just changes to a different type. TJ
