... You grasp the end of a spring that is attached to the wall and is initially in its resting position position. You pull it out until it is extended 0.1 m from its resting position, then push it in until it is compressed by 0.1 m from its resting position. Finally you return the spring to its resting ...

... A seagull (mass = 20 kg) is flying in a small circle 9 m above the ground. a) Calculate its gravitational potential energy. An angry fisherman shoots at the seagull. He misses, but the seagull, petrified and unable to move, falls straight onto the ground. The air friction is negligible. The fisherm ...

... A more general conservation of energy Conservation laws are probably the most important concept in physics and conservation of energy is among the most fundamental. Energy is always conserved when you consider a large enough system. When friction-like forces act, they transform kinetic energy into ...

A quantum phase transition seen from 0 to 600 K
... As concerns the low-temperature superconductivity, we found that – contrary to the old data obtained with less well controlled samples – superconductivity appears only in the rhenium-rich region beyond the quantum critical point at xc= 0.25. So that property is due to the addition of rhenium to the ...
