The scientist explained to us that the force of gravity2. What scientists think is that the Earth became differentbecause of small plants growing in the water on its sur-face.3. It is obvious to the students that they should get wellprepared for their future.4. The last time we had grea...
The force exerted by the object can be calculated as the product of the mass and the acceleration due to gravity. Answer and Explanation: We are given the following data: The given mass is m=65kg. The expression for the force of gravity exerted by me on ...
For computing the force of gravity, the mathematical formula is F=GMmr2, where G is perpetually fixed, G=6.7×10−11Nm2kg−2. This formula is employed when two objects are addressed and this formula concludes that any object that possesses mass possesses gravity....
The Earth is moving at quite a speed, moving at over a thousand miles per hour. 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 ...
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...
We have all experienced the force of gravity. It is what happens to you when you jump up into the air. Disappointingly, we tend to fall right back down to the ground. But what if we could switch gravity off? What will happen if the gravity vanishes? Buckey, an astronomer, says that...
physic物理问题英文6A.calculate the force of gravity on a 65-kg person in the following:a.at the surface of the Earth (R=6400km)b.at twice the Earth's radiusc.at four times the Earth's radiusB.Plot this gravitational force with distance.What pat
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 ...
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...
What is the force of gravity on Earth compared to Mars in The War of the Worlds? Describe the wood elves in The Hobbit. What is a key difference between a theme and a central idea? What tree is important in Walk Two Moons? What...
