Hipervinculo Física
Mass is a measure of how much matter, or material, an object is made of. Weight is a measurement of how the gravity of a body pulls on an object. Your mass is the same everywhere, but your weight woul ...

Michael Faraday was a 19th century English scientist who is credited with many great discoveries in the realm of physics and chemistry, specifically on the relationship between current and magnets, an ...
Hipervinculo Física
Electromagnetism is a cool (and useful) natural phenomenon. Electric current, which is the flow of electrons, creates its own magnetic field when in a closed loop. In conjunction with other magnets or ...

Total internal reflection is what happens when light enters a new medium, or material, at an angle larger than a critical angle. A critical angle is when the incident angle, or the angle at which ligh ...
Have you ever wondered why it takes more than just water to get your clothes and dishes clean? Detergent dissolves in water and attaches to things like dirt and whatever is staining your clothes to he ...
Nearly everyone has had some fun playing with magnets, trying to pick up different magnetic things, feeling the repelling force when pushing poles together, or even prying strong magnets apart. But ho ...

Have you ever seen a bug skate across the surface of water? This is made possible by the cohesion of water molecules on the surface of the water. When we say that water molecules are cohesive, we mean ...
Hipervinculo Física
Planets are generally spherical because of gravity. The gravitational force created by a massive celestial body (a planet-sized body) attracts surrounding things towards its center. Gravity is relativ ...
Hipervinculo Física
Lightning is the electronic discharge between particles in the air andclouds and the ground. Electricity is carried through current, or the flow of electrons, and lightning is caused by very large cur ...
Hipervinculo Física
Electricity is carried by current, or the flow of electrons. One useful characteristic of current is that it creates its own magnetic field. This is useful in many types of motors and appliances. Cond ...
