In today's lesson, you'll delve deeper into your investigation of friction and distance-time graphs. Begin by analyzing the provided pages 136 and 137. Formulate a question for Mr. Porter based on your reading to enhance your understanding. Next, explore various types of distance-time graphs, including instances of no movement, constant speed, and acceleration. Consider how these graphs would differ for various speeds. Complete the questions on page 139 (4 and 5) to reinforce your learning and draw conclusions from your friction investigation.
