This animation emphasizes that most waves are a moving disturbance pattern, that the pattern moves but not the material through which the waves moves. This is an important concept in the physics of waves.
This animation shows the effect of relativity on a ball moving in very high velocity that has a flashing lamp inside it. The viewer sees the length contraction and time dilation as compared with an identical ball that is ...
This animation shows how the speed of an object depends on the reference frame of the observer. This is a key concept in Einstein's theory of special relativity.
This animation illustrates the need to simultaneously mark the ends of a moving object in order to correctly measure its length. This is a key concept in Einstein's theory of special relativity.
This animation illustrates a thought experiment in the derivation of transforms for special relativity. This particular animation shows that lengths parallel to the motion must contract in order to be consistent with the ...
This animation illustrates a thought experiment in the derivation of transforms for special relativity. This particular animation shows that length perpendicular to the direction of motion will not be changed by change ...
This animation illustrates a thought experiment in the derivation of transforms for special relativity. This particular animation shows that two spatially separated event that are observed to occur at the same time in one ...
This animation illustrates a thought experiment in the derivation of transforms for special relativity. This particular animation shows that lengths parallel to the motion must contract due to high speed motion in order ...
