Teaching with Technology Cy- Seilias Physics and Photography
Seilias Physics and Photography is a very good web page with which students can see certain physical phenomena in three dimensions, so they can acquire a better understanding of them.
We use it for certain chapters in Physics where the use of the whiteboard is not effective enough to allow the students a better understanding. A very good example of this is the chapter on Oscillation.
When we wanted to show the connection between oscillation of a spring and circular movement, we connected to this web page in class and the students could see a simulation which helped them understand the connection better.
In a few words.. In Theory, Theory and Practice are the Same but In Practice They’ re Different.

In the simulation below press play
in order to see the movement of the body at
each point in time.
Observe the projection of the yellow point on the vertical axis. What kind of
movement does it perform?
Drag the yellow point so as to change its original position so that the oscillation
acquires a starting phase.
Drag the speed vector to change the linear speed and therefore the angular speed
also( R = constant).
Change the radius of the circular orbit to change the width of the oscillation.
Change the angular speed of the circular movement in order to see how the angular
frequency of the oscillation is affected.
Move the time runner in relation to the period so as to see the position of the point
at a certain moment in time t.
