For teachers looking to organize a video analysis session of a movement, one of the main challenges is often finding a suitable video. This is why we have created a free library of videos and chronophotographs, directly accessible from the FizziQ app. These resources can be easily downloaded and used immediately within the application.
Why use the video library
In the context of learning kinematics, the ideal approach is for students to record their own videos. This can be easily done with a smartphone, and the resulting videos can be directly analyzed with FizziQ. To assist students in this process, we have created a specific guide on the 7 best practices for recording a video for motion analysis.
However, in many cases, it may be useful for teachers to provide students with a pre-existing video. This is where the FizziQ video library becomes a valuable asset.
The free library of videos and chronophotographs offers several advantages:
Time-saving: No need to record your own videos; they are ready to use.
Optimized quality: Videos are recorded to ensure clear visibility and precise tracking.
Variety of scenarios: The library includes different types of motion to cover a wide range of physics experiments.
Direct access: Users can integrate these videos directly into FizziQ to begin their analysis without additional steps.
How to Download a Video in the FizziQ App?
Downloading a video from the FizziQ library is very simple:
Open the FizziQ app.
Tap on the "Motion Analysis" icon.
Select "Video Analysis" (the process is the same for chronophotograph analysis).
Click on "Video Library".
Choose a video from the list (an internet connection is required).
Add the activity to the motion analysis module.
What Types of Videos Can You Find?
The library contains a variety of videos suited to the needs of teachers and students:
Sports and Athletic Performances: Pole vault, ski descent (Olympics), speed skating, tennis, diving, football (penalty kick), badminton, track cycling, curling, javelin throw, discus throw, hammer throw.
Physics Experiments: Free fall, uniform and accelerated motion, friction forces, cycloid motion, simple pendulum and Newton's pendulum, collisions between objects.
Other: Droplet of dye in oil (time-lapse x15), collisions, SpaceX launches, cars, bicycles, trains.
New videos are regularly added to the library, including some created by our users. If you would like to share a video with us, you can contact us at juliette@fizziqlab.org.
Along with these videos, we have also created activities on motion and energy, which you can find here: 👉 Motion Analysis Activities
Chronophotographs: An Alternative to Videos
To introduce Motion Analysis, it is often best to start with chronophotographs. These sequential images capture different phases of motion in a single frame, allowing for precise observation of trajectories and speed variations. For more information on organizing a practical session using chronophotographs to study motion analysis, follow this link.
The FizziQ library offers a collection of original chronophotographs, enabling the study of a wide range of motions in class or independently.
It is also possible to photograph an existing chronophotograph from a book and analyze it directly within the FizziQ app. This can be particularly interesting for studying historical chronophotographs by Jules Marey or Berenice Abbott.
How to get fps and visual scale informations?
Many a correct physical analysis of the phenomena depends on having access to informations about the number of frames per seconds and the scale of the image.
The characteristics of the videos, such as format and frame rate, are automatically detected by the application. Most videos are recorded at 30 frames per second, but some have different frame rates (25 or 60 fps). These details are available for each video or chronophotograph.
Each resource also includes a visual scale, allowing students to precisely calibrate their analysis.
Conclusion
The FizziQ video library is a powerful tool that simplifies the teaching and learning of Motion Analysis. By providing optimized and ready-to-use videos, it enables students to focus on analyzing and interpreting motion rather than spending time on data collection.
