Physics principles and animal locomotion

    Physics principles and animal locomotion

    I am a physics final 4th year student ,
    My final year project is to Illustrate the Physics principles using animal locomotion(, behavior).
    E.g. :-Millipede leg movements - Longitude waves
    Video Illustration

    Snake movement - transverse wave

    Doppler effect- Insect movement on water surface(wave fronts)

    I am searching more relationship as in the examples mentioned above.
    Anybody interested and have more ideas pleases reply me.
    And I will be grateful to you if you reply with the links to other material which will strength this project.

    Thanking you.

    Regards Elil.

    According to the principle of conservation of momentum, to acquire a body a forward momentum should push back the material on which it is moving.
    The key is in the middle pair of legs of insects that creates subsurface vortices shape U, a few millimeters below the surface. Using the median of the total of three pairs of legs as a paddle, "rowing", forcing water behind those legs to push them forward. Although the rowing motion creates tiny waves, they do not play an important role in transferring momentum, which is necessary.

    There's a fair bit of aeronautics involved with birds...

    The fourier transform of snake movement makes up of sine functions, (transverse wave as you mentioned).

    If I understand you correctly, you don't really care whether the physics principle is actually involved in the locomotion process. You just look for controlled movements will look similar to physical processes. Is that correct?
