Your guide to physics on the web.
If you are looking for basic physics information, stay on this site. It's not just physics for kids, it's for everyone. We have information on motion, heat and thermodynamics, electricity & magnetism, light, and modern physics topics.
Energy exists in many different forms, such as heat, light, sound, electricity, and movement. It cannot be made of destroyed, just changed from one type of energy to another.
Electricity works because all objects are made of atoms, which contain a positively charged nucleus and negatively charged electrons. Electricity is the flow of negative electrons from one place to another.
Magnets are objects that can exert an invisible force called magnetism, which pulls on some metals such as iron and nickel.
Introduction to Waves
For the most part, in this section of Zona Land we will be discussing mechanical waves. Water waves and sound waves are examples of mechanical waves. Light waves are not considered mechanical waves. However, most of the mathematics and reasoning of mechanical waves applies to light waves.

Types of Color Blindness
Despite the name, color blindness doesn't actually mean that people see the world in black and white. In fact, more than 99% of all colorblind people can in fact see color. Because of this, the term "color vision deficiency" (CVD) is considered to be more accurate.
At CERN, the European Organization for Nuclear Research, physicists and engineers are probing the fundamental structure of the universe. They use the world's largest and most complex scientific instruments to study the basic constituents of matter – the fundamental particles. The particles are made to collide together at close to the speed of light.
Light behaving as ...
Scientists capture the first image of light behaving as both a particle and a wave.
