This study guide covers reference frames and relative motion in AP Physics 1. It explains how measurements of direction and magnitude depend on the observer's perspective. It focuses on inertial reference frames and how to convert measurements between them using vector addition/subtraction to determine observed velocity. The guide emphasizes one-dimensional motion and provides practice questions on calculating relative velocities.

Question 1 of 10
A person is sitting on a moving train 🚂. How does the motion of a ball appear to them compared to someone standing outside the train?
The ball's motion will appear identical to both observers
The ball's motion will appear faster to the person on the train
The ball's motion will appear simpler to the person on the train
The ball's motion will appear only in opposite direction to person on train
