- Early on, dense iron sank out of the magma oceans to form the metallic core, liberating enough gravitational energy to melt the entire planet. 更早期的时候,较重的铁自岩浆海中析出下沉,渐渐形成了金属成份的地核,下沉时释放出的重力位能足以把整个地球再次熔融。
- If you throw a ball into the air, it rises to a higher altitude but decelerates: it gains gravitational energy at the expense of kinetic energy. 如果把球丢到空中,高度增加,但速度减低了:动能的损失转变为重力位能。
- If we can change our position so it is more in line and more in harmony with gravitational energy, then our tendency to randomness, disorder, and deterioration will decrease. 如果身体的姿势和地球重力和谐起来的时候,身体的散满、无序、日趋恶化就会减少并改善。
