The light travel directly through the vacuum and reaches earth
The pull of Earth's gravity gives all matter on Earth weight, which is the force exerted on an object due to gravity. This weight is the reason why objects fall towards the Earth and why all matter on Earth experiences a downward force.
just cos
A scale that measures weight would give a different measurement in space than on earth for the same object.
OK, your question was "What percent of Earth's gravity does Uranus have?" We [the website] could just give you the clear answer that you wanted. But we're gonna do better than that. How about we give you the percentages of Earth's surface gravity for the surface gravityofall theplanets, and not just for Uranus. This answer is extended for a better quality answer. Here you go. Hope this helps:Mercury: 38%Venus: 91%Earth: 100%Mars: 38%Jupiter: 254%Saturn: 108%Uranus: 91%Neptune: 119%Youwill findanswers for the "gas giant" planets, such as Uranus, vary a bitfrom other sources because it's hard to give an exact answer in those cases.
Stars like the sun give off light through a process called nuclear fusion. In the sun's core, hydrogen atoms fuse together to form helium, releasing a tremendous amount of energy in the form of light and heat. This energy is then radiated out into space, providing light to the planets, including Earth.
they give us energy to survive
No it doesn't, earth's gravity is only making the moon orbiting the earth not give the moon gravity.
No. Earth's gravity is due to Earth's own mass. The moon has its own gravity due to its mass, but that gravity is much weaker than Earth's.
You have to eat food only to give energy. It is because zero gravity environment can cause indigestion.
With out gravity planets would go flying off into space
Yes, approximately. Because of higher velocity, astronauts age slightly less than their counterparts on earth, when they are in space, but only by a tiny amount.On the other hand, weightlessness and radiation contribute to bone loss and other ill health effects; so it might be said that even though time is slightly slowed-down for astronauts, they can suffer a deterioration of their health.
Yes. Earth's*
a book sitting up on a shelf. gravity can potentionally pull it down if pushed.
Gravity is a result from mass (i.e. the greater the mass an object has the more gravity force it will inflict on its surrounding objects). Taking your question literally, if there were no gravity, then there would be no Earth; as to have no gravity the mass of the body must be zero. Therefore you'd be left floating in space. Now if all of a sudden (for some comical and unscientific reason) the Earth's gravitational pull would be switched off, our atmosphere would dissolve, airplanes would continue to fly up into space, and a simple jump would give you enough escape velocity to reach space. So you wouldn't necessarily "fall of the Earth", you'd more or less float away in a Zero-G environment (which happens to mean zero-gravity).

The potential energy of a stone on Earth's surface depends on its mass, height above the ground, and acceleration due to gravity. The potential energy is given by the formula PE = mgh, where m is the mass of the stone, g is the acceleration due to gravity, and h is the height above the ground. On Earth's surface, the height above the ground is considered to be zero, so the potential energy of the stone would also be zero.
No, the Earth does not give off as much energy as it takes from the Sun. The Earth reflects, absorbs, and radiates a portion of the solar energy it receives, but it does not emit an equal amount back into space. Some of the energy is also used in processes like photosynthesis, weather patterns, and ocean currents.
