In physics, motion is a change in position of an object with respect to time and its reference point. Motion is typically described in terms of displacement,velocity, acceleration, and time. Motion is ...

I saw it again. This time it was an introduction to an interesting online look at introductory physics. I was excited---but then, I wasn't so excited. Right there in the first video they talked about ...

A bold paper which has highly impressed some of the world's top physicists and been published in the August issue of Foundations of Physics Letters, seems set to change the way we think about the ...

Friction is an intrinsic physical phenomenon to curling. Without it, objects in motion would move endlessly, without slowing down. This would cause many safety-related problems: Cars or trains could ...

Researchers found that people make much more accurate estimates when they have access to information about both the speed of a moving object and the timing of its rhythmic patterns. Catching a ...
