Newton's cradle twist

Newton's Cradle

Recently, there is discussion about pendulum wave effect produced using the Newton's cradle. There are many YouTube videos about pendulum waves. Having seen some of these "amazing" wave effect, I thought that VRMath2 Editor should be able to produce a fake, but good enough to show the effect of pendulum wave simulation. And here you go, see the 3D simulation below.

Hydrochloric Acid

Hydrochloric Acid planetary model with protons and neutrons

Everything contains atoms. Atoms are the basic units of matter and the defining structure of elements. Atoms are made up of three differently charged particles: positively charged protons, neutral neutrons and negatively charged electrons. Protons and neutrons are heavier than electrons and reside in the centre of the atom, called the nucleus.

The Potassium Atom

Potassium is a chemical element classified the atomic symbol 'K' on the Periodic Table. As the seventh most abundant element on Earth (2.6% abundance in Earth's crust), potassium is found in a wide array of industries, despite being commonly known for its integral role as a mineral that allows human cell function and its presence in bananas. Some applications of potassium are (but not limited to) potassium-based fertilisers, pharmaceuticals and manufacturing. Discovered in 1807 by Sir Humphrey Davy, its abundance and simple atomic structure has allowed for exhaustive research and application regarding potassium.

Carbon atom

Carbon is one of the most abundant atoms in the universe. It is able to form many compounds, such as diamond, graphene and graphite.

    NaCl Lattice Blog Entry FINAL (Ryan Gray ASC091C)

    NaCl Lattice

    By Ryan Gray ASC091C

    This model is of a salt crystal lattice, with the chemical formula NaCl. Its different properties allow it to have many uses in society, including as a preservative, flavouring and currency. Salt demonstrates ionic bonding and its structure makes it interesting to model, because the crystal lattice can continue on forever and doesn't have a specific number of atoms like water does, with each water molecule consisting of one oxygen and two hydrogen atoms. For the purposes of this project, I limited my model to a 3x3x3 cube so it could be easily seen. The distance between the atoms was also expanded to allow the bonds to be more clearly viewed.

    Atomic Model

    Here is my first attempt at a transforming model, I found it useful to give the centre a texture to conceptualise what was "spinning".  I have not yet worked out how to roll up and tilt right at the same time (moving both axis').

    3d gears

    As an update to the 2d involute (curved teeth) gears, I modified the program to produce 3d (extruded) gears. This required a change in drawing tactics.
