题目Gravity is what makes objects ___. A. fly up B. stay still C. fall to the ground D. move sideways 相关知识点: 试题来源: 解析 C。解析:文章中明确提到“Gravity is what makes objects fall to the ground.”,重力是使物体落到地面的原因。反馈...
选项 B“Objects would fall to the earth”是物体落向地球,与假设不符;选项 C“Objects would stay on the moon's surface”在没有重力的情况下物体不会仅仅停留在月球表面;选项 D“Objects would disappear”物体消失与假设无关。选项 A“Objects would float on the moon”符合没有重力时物体漂浮的情况,...
What is the physical property that gravity has that enables it to make an object go faster or, if it is resting on the ground, have weight? That means it can do work: it gives objects kinetic energy. Where does that ability come from and where does the energy (the gravitational potentia...
More recent theories of gravity express the phenomenon in terms of particles and waves. One view suggests that particles called gravitons cause objects to be attracted to one another. However, gravitons have never been observed. Another theory involves gravitational waves or gravitational radiation, ...

What is gravity and what does it do? We all know that gravity exists and that it keeps us on the ground, gravity is a force that pulls objects towards itself. The word gravity comes from the Latin wordgravitaswhich means weight.
objects on Earth (question: How does gravity affect motion of objects on Earth?), specifically how gravity pulls objects towards the center of the Earth. I will then (in the rest of my unit) focus on the question, ―How do forces impact the motion of objects on Earth?‖ By the ...
How can objects become electrically charged? What are gravity waves in meteorology? What determines crystal size? Does density change with state of matter? How do you describe the wave nature of an object? How does an object become negatively charged?
How does general relativity work? To understand general relativity, first, let's start with gravity, the force of attraction that two objects exert on one another.Sir Isaac Newtonquantified gravity in the same text in which he formulated his three laws of motion, the "Principia." ...
What is specific gravity? A closed system consists of 4 objects. Initially, object A has 140 J of energy, object B has 175 J of energy, object C has 148 J of energy, and object D has 191 J of energy. After 167 s have passed, object A has 5 J of energy, object B has 72 J...
