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 ...

A basic pendulum is a mass at the end of a string that swings back and forth. It seems simple, and it appears in most introductory physics textbooks. But it's not a trivial problem to solve for the ...

Check out this video demo: So, that is just plain water. If I am careful, I can make that thin aluminum disk stay on the surface of the water. This is not the same as floating in Archimedes principle.

In the absence of substantial B g, this tension force is much reduced. This leads to the eruptive behaviour shown in Extended Data Fig. 3, where the J T profile remains relatively uniform throughout ...
