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, ...

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 - ...

Newton's Second Law states that force equals mass times acceleration. This can be investigated using a set-up like this one. You can use this set-up to investigate how changing two separate factors, ...
