Beth Harris, a Raleigh mom and long-time science educator, returns with a fun and easy experiment where kids can test their strength with friction. Beth Harris, a Raleigh mom and long-time science ...

Without the force called friction, cars would skid off the roadway, humans couldn't stride down the sidewalk, and objects would tumble off your kitchen counter and onto the floor. Even so, how ...

Memory fault: friction study could provide new insights into why earthquakes happen. (Courtesy: iStock/allanswort) Experiments by Sam Dillavou and Shmuel Rubinstein at Harvard University have, for the ...

A suspended apparatus used to minimize friction during the experiment. The heavier brass cylinder and lighter ping-pong ball collide repeatedly against the transparent wall, reproducing 31 collisions ...

Topological insulators are innovative materials that conduct electricity on the surface, but act as insulators on the inside. Physicists have begun investigating how they react to friction. Their ...
