He says that we must therefore give up the idea of gravity as a force and instead think of gravity as being the result of curving space and time. The result being that it creates the impression of objects being attracted to each other. Roughly speaking, Einstein is saying that we believe ...
The force of gravity acting on an object is also that object's weight. When you step on a scale, the scale reads how much gravity is acting on your body. The formula to determine weight is [source: Kurtus]: weight = m x g where m is an object's mass, and g is the acceleration...
The hope is that one day gravity might be too, when in a third iteration we uncover what quantum properties of mass, energy, space and time combine to make gravity at a fundamental level. At the moment, however, the quantum particle that transmits gravity, the “graviton”, remainsstubbornl...
Earth's gravity comes from all its mass.Gravity also gets weaker or stronger with distance. So, when the objects are closer to each other, the stronger will be their gravitational pull, and when the objects are distant to each other, their gravitational pull will be weaker. It is measured ...
With a mass that big, I guess gravity would start to pull in more and more material faster, right?MALE PROFESSOR: Material, meaning gas. It would rapidly pull in more and more gas from the accretion disk, so you end up with a solid core of rock, metal and ice surrounded by massive...
lf a comet on one of these long period orbits at some point comes close to Jupiter or Saturn or one of the other planets, then the pull of that planet's gravity might alter the orbit, maybe make it much shorter.So this comet, if it happens to pass by a planet just the right way...
What does the system count on to pull the stored water down? A. Turbines. B. Gravity. C Tunnels,D) Electrcity30. What is the third paragraph mainly about? A. The main function of Nant de Drance. B. The connection of the two reservoirs. C. The comments on the project. D. The ...
Rain falls from clouds for the same reason anything falls to Earth.The Earth's gravity pulls it.But every cloud is made of water droplets or ice crystal(冰晶).Why doesn't rain or snow fall constantly from all clouds?The droplets or ice crystals in clouds are extremely small.The effect ...
Mass, sometimes confused with weight, is the amount of matter an object contains — as mass increases, so does gravitational pull. Black holes, astronomical objects often seen in science fiction movies, are so massive that light can't escape them. A grain of salt's gravity is much smaller ...
What is the opposite of gravity?Force:The force can be defined as a quantity that applied to the object to change the position of the object or try to change the position of the object. The force applied depends upon the mass of the object and the acceleration of the object. The force...
