The larger the mass of an object, the greater the gravitational force it exerts D. Gravity affects the motion of planets in the solar system 相关知识点: 试题来源: 解析 B。解析:选项A,重力是一种使物体相互吸引的力,这是正确的。选项B,重力不仅仅存在于地球,宇宙中其他天体之间也存在重力,所以该...
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 ...
Gravity affects everything, at all scales, according to the same basic formulae. So, as scientists started to examine the universe on a larger scale, they noticed these gravity formulae delivered increasingly wrong predictions. As early as the 1930s, Fritz Zwicky discovered that galaxies in th...
Identify the force applied to the bicyclist. This information should be given in the problem statement or can be calculated based on other provided data. Calculate the acceleration using Newton's second law of motion, which states that the force acting on an objec...
or in the case of a pendulum clock, have it swing powered by the gears. Either way the principle of periodic motion affects the pendulum. The force of gravity pulls the weight, or bob, down as it swings. The pendulum acts like a falling body, moving toward the center of motion at a...
(4) What is the main topic of this passage? [ ] A. Types of droplets B. Droplets and ice crystals C. How gravity affects clouds D. The cause of rain (5) According to the passage, which of the following is not true? [...
Field Force Operates across a space. The sun's gravitational Field Force affects planets from a vast distance. 5 Common Curiosities Can you name a force that works without objects touching each other? Yes, gravity is a Field Force that works without objects physically touching each other. 12 ...
