Today in class...

Today, we started class by discussing how a single point particle can be thought of as a piggybank. and money as a whole is considered energy. i thought that was a cool analogy!!

Energy is put into an object, but then it must leave the object at some point. if more energy is put into an object than the amount that leaves, the object is gaining energy. if more leaves an object, it is losing energy.

Then, we looked at our graphs. K should be between 400N/m and 800N/m. The force of the spring is opposite the stretch. Just as a review: work equals force times change in displacement. (W=F*change x)

Homework is to finish 5b and start 5c. tomorrow's scribe is Sana!!
