Vernier Video Physics uses video data to calculate velocity over time. Vernier Software & Technology has rolled out a new application that works with the iPod touch, iPad, or iPhone to collect physics ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

Scientists often make measurements. The physical quantities they measure fall into two categories: scalars and vectors. Scalar and vector quantities are treated differently in calculations. Motion - ...

Using modified laws of gravity, researchers have closely predicted a key property -- velocity dispersion -- measured in faint dwarf galaxies that are satellites of the nearby giant spiral galaxy ...

An object being fired from a cannon is also a collision where momentum must be conserved. As the momentum before the 'collision' is zero, the momentum after the collision is zero. In physics, this ...
