Four-stroke Otto engine

This animation demonstrates the type of engine most commonly used in cars.

Voyager space probes

The Voyager space probes were the first man-made objects to leave the Solar System. They gather data about outer space and carry information about humanity.

The Moon

The Moon is the Earth's only natural satellite

Structure of nitrogen molecules

This animation demonstrates the structure of nitrogen molecules, with one sigma and two pi bonds holding the atoms together.

Newton’s Laws of Motion

This animation demonstrates Sir Isaac Newton's three laws of motion that laid the foundation for classical mechanics.

Our astronomical neighborhood

Solar eclipse

When the Sun, Earth, and the Moon are arranged in a straight line, the Moon can partially or completely obscure the Sun.

The life-cycle of the Solar System

The formation of the Sun and the planets started with the contraction of a dust cloud about 4.5 billion years ago.

Transparency

This animation explains transparency and opacity, the principle of radiography, and the light-absorbing properties of materials.

The development of celestial mechanics

This animation introduces the studies of astronomers and physicists whose works fundamentally changed our view of the universe.

Maglev Trains

One of the most modern means of transportation is the Maglev, capable of traveling at speeds of over 400 km/h (248.6 mph).

Dynamo (intermediate)
