Why is pancake syrup an example of a resistive force? Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force ...

Chalmers researchers have developed a simple, light-based platform to study the mysterious “invisible glue” that binds materials at the nanoscale. Gold flakes floating in salt water reveal how quantum ...

“I am one with the Force, the Force is with me.” In an hour, we will take on some of the science behind the movies – experimenting with forces and motion, using angles of incidence and refraction to ...

Water trapped inside tiny molecular cavities behaves in a surprisingly energetic way, pushing outward like people crammed in an elevator. When a new molecule enters these narrow spaces, the confined ...

When humanity first started studying motion, circles posed a peculiar puzzle. Why do planets sweep endlessly around the Sun without flying off into the void of space? Why does a stone swung on a ...
