In this document, I break down the two parts of Newton's First Law of Motion. Students are asked to discuss and provide examples of objects at rest and objects moving at constant velocity. Then they are asked to explain how an unbalanced force can cause a change in its motion. I included an easy to understand answer key for students to better understand the examples and explanations. There are also four pictures to provide visual examples of Newton's First Law. This lesson really got my students to understand the meaning of this law.
