2015 #1 Free Response Question - AP Physics 1 - Exam Solution

The video tutorial covers a problem from the 2015 AP Physics exam involving blocks connected by a string over pulleys. It explains how to draw free body diagrams, derive the acceleration of the blocks, and the impact of adding a third mass. The importance of accurately drawing and labeling diagrams is emphasized, along with understanding the concepts without relying on numbers.

What is the relationship between the forces acting on the blocks and their respective accelerations?

How does the absence of friction between block three and the table affect the system's dynamics?

Describe how the addition of block three changes the free body diagrams for the system.
