Can you build a tool to retrieve a ping pong ball from as far away as possible, using nothing but paper, string, tape, and paper clips? Give it a try and enter your design in the 2023 Science Buddies Engineering Challenge for a chance to...

This video discusses the three common states of matter: solid, liquid, and gas. The video starts with an introduction and shows the three states of matter: a beaker (solid), water (liquid), and air (gas). Then, the video explains the...

First we solve for the electric potential along the axis of a uniform thin ring of electric charge. Then we use that electric potential to solve for the electric field at the same location.

The electric potential difference in a uniform electric field is derived and used to show lines of equal electric potential or equipotential lines. Equipotential lines and surfaces of point charges and dipoles are shown. The equation for...

Calculus is used to derive the equation for the electric potential difference between two parallel plates of equal but opposite charge. It’s a uniform electric field. The significance of the negative in the equation is explained.

A number lying in the middle between two numbers.
