This PhET simulation virtual lab on force and motion is a great way to introduce students to the concept of force, mass, and acceleration. By the end of this activity students should be able to observe the relationship between force, mass, speed, friction, and acceleration and answer conceptual concepts. This lab consists of 9 pages, 4 parts, with a total of 28 questions. The lab is laid out as the following:Part 1: Net Force- questions 1-5Part 2: Motion- question 6-10Part 3: Friction- questions
