Life in space is difficult but exciting. There is much less gravity in space, so things in the spaceship float in the air. Before we go to bed, we need to 11 our sleeping bags to something. We are already hundreds of thousands of 12 away from the Earth. Tomorrow, we will land on ...
There is no gravity on the Moon, so people can enjoy floating there. If you weigh 43kg on Earth, you will weigh only 11kg on the Moon.There are many interesting places such as craters, mountains, and lava plains(熔岩平原) on the Moon. There is no air on the Moon, so people can'...

there was insufficient gravity to hold on to its atmosphere, the drop in atmospheric pressure was inexorable, and the solar wind swept it all away.火星的悲剧在于它太小了，而且陷入了致命的漩涡。由于
s because the planet is about to get very, very hot. You see, the sun’s tremendous gravity pulls the Earth right toward it. Meanwhile, the planet is trying to whiz away in this direction. This tug of war keeps us in o...
The only noticeable real effect of the moon on the Earth are the tides. Tides exist because while Earth pulls on the moon, the moon’s gravity pulls back on the Earth. Since the strength of gravity gets weaker with distance, different parts of the Earth feel a slightly different pull, ...
Actually, it is. You see, sea level has always been at equilibrium with Earth’s gravity (which pulls the water towards the center of the Earth). Furthermore, due to the rotation of the planet, an outwardcentrifugal forceis generated, which makes a ‘bulge’ along the center of the plan...
What If Earth Gradually Stopped Revolving Around The Sun? The effects would be less dramatic, but equally devastating, in this alternative case. With no outward centripetal force to compensate for the strong inward tug of the Sun’s gravity, Earth would begin to fall towards the Su...
What will be the acceleration due to gravity on the surface of the earth? View Solution If the distance between the earth and the Sun were half its present value, the number of days in a year would have been View Solution If the distance between the earth and the sun were half its ...
