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 ...

The ability of primates to sense the direction and speed (together, the velocity) of moving objects depends on an elaborate sequence of computations that have been investigated in psychological, ...

Driving a spacecraft around a planet isn’t anything like driving on a planet. A physicist explains orbital navigation.

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 ...

Speed is the rate at which something moves. Fast-moving objects have high speeds, slow-moving ones have low speeds, and objects with no movement have zero speed. Velocity, on the other hand, is speed ...

For example, an elephant has no momentum when it is standing still. When it begins to walk, it will have momentum in the same direction as it is travelling. The faster the elephant walks, the larger ...
