Visualizer, capture your motion data and video automatically and begin analyzing
your data right away. Use either a webcam or, for more accurate timing
and higher resolution, use an ordinary digital video camera plugged directly
into a computer to gather motion data in a plane.
Motion Visualizer—captures and displays, in real-time, the position,
velocity, and acceleration of one or two objects. It is ideal for elementary
as constant and accelerated motion where the visual connection between the
motion and the graph is crucial for understanding. However, for more advanced
Motion Visualizer, like its older cousin, Motion Visualizer 3D provide unique
capabilities. They are the only tools in physics education that capture all
the relevant motion variables making them ideal for momentum and energy studies,
for instance. Data imports directly to Excel and other analysis software enabling
a whole range of quantitative study.
Key features provided by Motion Visualizer
- Web camera provides simple setup and low-cost (see requirements).
- Visual methods
