Why is this app so great? Its biggest appeal is that it analyzes videos you record on your smartphone and automatically tracks the movement of an object. It also instantly generates graphs that show how the object\u2019s position (x-t) and velocity (v-t) change over time.<\/p>\n
This is essentially a digital and more advanced version of the classic ticker-tape timer experiment. By visualizing the motion with this app before a traditional experiment, students can get a clear picture of “what we’re doing” and “what we’re trying to find out.” Watching the trajectory and the shape of the graphs appear in real-time will help spark those “why?” and “ah-ha!” moments in your students.<\/p>\n
You can use it as a dynamic introduction to a lesson to show them how cool this is, or have students record and analyze the motion of everyday objects themselves as part of a hands-on project. This one app can make your science class more fun and engaging.<\/p>\n
A Practical Guide to Using Vernier Video Physics in Your Classroom
\nWhat You’ll Need<\/p>\n
- \n
- A smartphone or tablet with the Vernier Video Physics app installed<\/li>\n
- An object to film (a ball, weight, toy car, etc.)<\/li>\n
- A simple, uncluttered background (a plain, solid-colored wall is best)<\/li>\n
- A ruler or measuring tape (to set a scale for distance)<\/li>\n<\/ul>\n
