Lifting heavy loads using a rope running over a roller does not have to counteract the friction. This film explains how adding a second roller means that only half as much force has to be applied. Multiple rollers in the right sequence create a practical pulley. We look at the physical basics of these tools.

The moon does not shine itself, but only reflects the light of the sun. That is why the phases of the moon depend on it. The film shows how the moon changes in our perception depending on the angle it is at to the sun. At an angle of zero degrees it is new moon, at an angle of 180 degrees it is full moon.

If the curvature of a curved mirror is convex, it distorts the mirror image. If it is concave, this is also true, except that the image is also upside down. The film explains why this is so and how the laws of reflection explain it. In addition, the video shows possible applications for everyday life.

For a surface to reflect light, it must be very smooth. A regular reflection is given, for example, by processed glass and metal, which are used to make mirrors. The film explains the law of reflection, the creation of illusions through partial reflection, and that the mirror image is a result of our own perception.

The topic of this video is the relationship between voltage and amperage. The film introduces the units of measurement volts for electrical voltage, watts for power, joules for energy, and amperes for amperage. It explains why the higher the voltage, the lower the amperage needed for certain outputs.

The invention of the diode was soon followed by the development of another electrode - the triode. This was the first amplifier. These amplifiers were used extensively until the transistor almost completely replaced them. As the video shows, electron tubes are now only used in high-end guitar amplifiers.

With the colours blue, yellow and purple, all colours can be produced. This is due to subtractive colour mixing: the colours act like a filter that prevents you from still seeing the original colours. The video explains understandable how the absorption spectrum of the filter makes some colours visible.

The physical term work is defined as the force exerted on a body in a certain way. In physics, a distinction is made between the work of lifting, acceleration, deformation, tension and friction, as the video explains with the help of examples from everyday life. The unit used to measure work is the joule.
