A book of mass 600 g has 12 J of gravitational potential energy. How high is it above the Earth’s surface? (g = 10 N/kg)? From the principle of conservation of energy, energy can never be ...

A constellation of satellites orbiting 250 miles above Earth’s surface shows how solar and wind have taken off in recent years: Here’s what renewable energy sites looked like eight years ago.

I n northeastern France, a groundbreaking discovery has unveiled a vast reservoir of hydrogen hidden beneath the Earth's surface. This revelation has the potential to reshape the global energy ...

Gravitational potential energy is the energy an object has by virtue of its position above the surface of the Earth. When an object is lifted, work is done. When work is done in raising the height ...

As global electricity use grows, the strain on traditional energy sources increases. Renewable options like wind and solar ...

Scientists have discovered that water moving over surfaces generates significantly more electrical charge than previously believed, particularly when it sticks and then slips past tiny obstacles. This ...

Europa, one of Jupiter’s intriguing moons, is hiding an ocean beneath its icy shell — an ocean that might harbor alien life. NASA's Europa Clipper mission is on a quest to investigate whether the ...

However, Katayama and Akamatsu have interpreted these cracks as potential evidence for water ... which uses "electrical energy . . . as a wave source" that "monitor[s] seismic wave energy" on ...

As global electricity demand grows, traditional energy sources are under strain. Oceans, which cover more than 70% of Earth's surface, offer vast ...
