" Earth itself would most likely break apart into pieces and float off into space." A similar fate would happen to the Sun. Without the force of gravity to hold it together, the intense pressures at its core would cause it to burst open in an explosion. The same thing would happen to...
Gravity keeps the moon where it's supposed to be — in orbit. Peepo / Getty Images Gravity is a force that we experience every day, yet it remains somewhat of a mystery. It's the reason we stay grounded on Earth and why objects fall when dropped. Although there are several theories ...
If there were no gravity on the earth, what ___ different our lives be? A. would B. will C. should D. can 相关知识点: 试题来源: 解析 A。本题考查虚拟语气在名词性从句中的用法。在表示与现在事实相反的假设时,从句用一般过去时,主句用“would/could/should/might+动词原形”。本题中表示如...
If you turn something around your head on a string(细绳), it goes around in a circle until you let go of the string. Then it flies off in a straight line. ‘Switching off’ gravity would be like letting go of the string. Things not attached to the Earth would fly off in a ...
What Is the Force of Gravity? If you throw a ball up, it will come down again. What makes it come down? The ball comes down because it is pulled or attracted towards the Earth. The Earth exerts a force of attraction on all objects. Objects that are nearer to the Earth are attracted...
①Turnedoff+heGravityWhat would happen if the gravity(重力) on Earth was suddenly turned off?Supposing we could magically(神奇地) turn off gravity, would buildings and otherstructures(建筑物) float away? What happened would depend on how strongly thethings were attached(粘上) to the Earth. T...
On Earth, the acceleration of gravity generally has a value of 9.806 m/s2 or 32.1740 f/s2. Since this is just a different scale for measuring acceleration, it not only applies to gravity, but can be used to quantify any acceleration. How g-force relates to harsh driving As mentioned, ...
The planet in solar system with the strongest force of gravity is Jupiter(木星).The Moon is smaller than the Earth. This means that it has less gravity than the Earth. Things will weigh less on the Moon than on the Earth. If you weighed 60 pounds on the Earth, you would weigh about...
