I'm currently in the middle of a summer section of introductory physics - the algebra based version. I've come to the realization that perhaps we expect too much from the students. My typical summary ...

An introduction to Coulomb’s Law and electric fields explained in a clear and simple way. Learn how electric charges interact, how force depends on distance, and how electric fields describe these ...

One of the things I really like about the Matter and Interactions curriculum that we're using for introductory physics (and that I'll miss when we stop using it next term) is that it has a really ...

The first evidence of a gravitational wave detected 100 years after Einstein imagined it -- proof that space actually vibrates -- drew standing-room only enthusiasts to two explanatory sessions this ...

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 ...
