Matching (10 points)

Examine all the paired pictures. The paired picture on the left is the initial energy of the system and on the right is the final energy of the system. Match the picture to the bar chart labeling the initial energy forms and the final energy forms of the object(s): for example, A1, B2, and C3 .

Answers:

___________, ______________, _______________

Ranking Tasks (10 points)

Rank each picture by final speed at the ground from least to greatest when ball reaches 0 m. In each picture, the vector shows the initial speed. If there is no vector, then the object is being dropped.

Answers:

Written Response (10 points)

Explain how each graph illustrates conservation of energy when a ball is thrown into the air and when a pendulum is swinging back and forth. For each explanation, describe what is happening at the five key points labeled as letters on the time axis.
