In this lesson, students will delve into Newton's First Law of Motion, also known as the law of inertia. We will explore why objects continue to move when forces cease to act upon them. Through investigations and examples, students will understand Galileo's contributions to the concept of inertia and the dependence of velocity on the frame of reference. The agenda includes hands-on activities, discussions, and quizzes to reinforce the learning objectives. Students will apply their knowledge through an engaging physics talk and collaborative investigations.

Do Now • A train is traveling at 30 m/s. A passenger on the train tosses a ball up in the air and it comes right back to him. A bystander sees the passenger from road next to the tracks the toss the ball through the window of the train. How fast is the ball moving to the bystander?
