In this lab, you will continue to explore motion graphs, this time focusing on velocity and acceleration. The main idea is for you to become comfortable at translating back and forth between graphs and real-life motion, and to understand acceleration at a deep, intuitive level. Even if you found the last lab easy, parts of this lab will challenge you. Particularly hard questions are marked with a star or a double-star. As you know, acceleration is the rate of change of velocity with time. Whenever the velocity changes, there is an acceleration
