Atoms are composed of three particles with an electric charge: electrons, protons and uncharged neutrons. Electrons have a negative charge, and protons have a positive charge. The negative charge of ...

A force is a push or a pull that acts on an object due to the interaction with another object. Force is measured in newtons (N). Forces are divided into contact forces and non-contact forces. A force ...

You're sitting in physics class, working on a traditional problem involving forces and acceleration, when you start to wonder where these terms even came from. Were they just dreamed up to bring ...

This is a cooler physics problem than I initially realized. It goes something like this. A block has a mass of 1 kg and is placed on a vertical wall such that the coefficient of static friction is 0.5 ...

Born 175 years ago, James Clerk Maxwell carried out the first profound unification of nature’s forces. Francis Everitt examines the immense contributions of the greatest mathematical physicist since ...
