句意:牛顿其实已经研究重力很多年了,一直在思考苹果是如何从树上掉下来而不是向上掉的。 inside在……里面;off离开;up向上;down向下。由上文“Newton had actually been studying gravity and thinking about how apples fell down from a tree”可知,此处指苹果是向下掉的而不是向上掉。故选C。反馈...
. People have learned that Isaac Newton once 1 when he was thinking under an apple tree. 2 he was woken up by an apple falling on his head. He jumped up, shouting, “Gravity made the apple fall!” Did the apple really fall on him? No one 3 for sure. The story of the ...
Sir Isaac Newton discovered gravity about 300 years ago. The story is that Newton saw an apple fall out of a tree. When this happened he realised there was a force that made it occur, and he called it gravity. Ocean tides are caused by the gravity of the moon. If you could travel ...

Sir Isaac Newton developed laws to describe both. Newton's Second Law (_Fnet= ma_) applies to any net force acting on an object, including the force of gravity experienced in the locale of any large body, such as a planet. Newton's Law of Universal Gravitation, an inverse square...

故正确答案为[C]。 【真题例句】In some states, for example, jury duty was limited to persons of supposedly superior intelligence, education, and moral character. 例如,在一些州,陪审团职责仅限于那些被认为智商、学历和道德品格更高的人承担。反馈...
The Gravity Formula The general formula for gravitational attraction is given by Sir Isaac Newton’s law of universal gravitation. This formula is mathematically expressed as: ( F = G frac{m_1 m_2}{r^2} ) In this formula: Frepresents the gravitational force between two objects. ...
From Sir Isaac Newton’s law of gravitation, we understand that any two objects in the universe exert a force of attraction on each other. This relationship is directly related to the mass of the two objects and the distance between them. The greater the mass of objects and the shorter the...
