When a ball hits the ground, it temporarily deforms upon contact. This deformation directly depends on the elastic properties of the material it is made...
If an object floats or sinks, it is primarily due to Archimedes' principle, an upward force exerted by a liquid on any object submerged in...
A inflated balloon has an internal pressure greater than the external pressure. This is because the air inside pushes against the walls in all directions, putting them...
A balloon, usually made of latex, is an excellent electrical insulator, meaning it retains static charges very well on its surface. When you rub it...
When you prepare bread dough, you add yeast. This yeast is actually made up of microscopic organisms: baker's yeast, fungi that love to eat the...
Specular reflection is simply when a ray of light bounces off a smooth surface rather than passing through it or being absorbed. For a mirror...
Light typically travels in a straight line, but when it passes from one medium to another different one (for example, from warm air to cold...
Everything around us is made up of molecules that are constantly moving due to heat. The hotter an object gets, the more its molecules become...
Leonardo was interested in everything, from mechanics to human anatomy, including drawing or studying the birds flying above his head. This insatiable curiosity constantly led...
According to Einstein and his theory of general relativity, gravity is not simply a force. It actually corresponds to a deformation of space-time caused by...
