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, ...

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 ...

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 ...

Velocity-time graphs show how the velocity (or speed) of a moving object changes with time. These graphs also show if the object is moving at a constant speed or accelerating, decelerating, or still.

I haven't always paid close attention to gravity. It's kind of a mundane subject. Gravity just always seems to be hanging around, and I take it for granted. I remember learning in school about how ...
