Chapter 10 Quiz - Motion (Holt)

10 Questions | Total Attempts: 263  Settings  Motion is the action or process of a physical body being moved. There is a way in which one can calculate speed and we covered it in class as we tried to understand the laws of motion and how to calculate how far or fast an object may move. Do you believe you fully understood chapter 10 section one on measuring motion? Test your understanding by taking the review quiz below.
