How far must you go to escape gravity?

Vocabulary1. Blasto Definition: To hit or damage something with a sudden, powerful force.o Sentence: The fast-spinning star blasts its neighbor with strong energy.2. Pulsaro Definition: A type of neutron star that emits regular pulses of radio waves and other electromagnetic radiation.o Sentence: The Black Widow Pulsar is a well - known pulsar that rotates rapidly every few seconds.3. Approximationo Definition: Something that is almost correct but not exact.o Sentence: Newton’s law of gravity is a useful approximation for our daily life.4. Deviateo Definition: To turn away from a normal or expected course.o Sentence: The curvature of spacetime makes light deviate from a straight path.5. Spacetimeo Definition: A four - dimensional continuum combining the three dimensions of space and the one dimension of time, proposed by Einstein's theory of relativity.o Sentence: Gravity is generated by changes in the curvature of spacetime around massive objects.6. Curvatureo Definition: The measure of how much a curve or surface deviates from being flat; in physics, it refers to the bending of spacetime caused by mass.o Sentence: The curvature of spacetime near Earth is strong enough to keep the International Space Station in orbit.7. Orbito Definition: The curved path of an object around a point in space, especially around a celestial body like a star or planet, due to gravity.o Sentence: The International Space Station travels in a stable orbit around the Earth at an altitude of about 400 kilometers.8. Microgravityo Definition: A condition in which the force of gravity is very weak, causing objects and people to appear weightless, as experienced in space orbit.o Sentence: Astronauts experience microgravity because the space station is constantly falling toward Earth while moving forward at high speed.9. Masso Definition: A measure of the amount of matter in an object; it determines the gravitational force the object exerts and experiences.o Sentence: Every object with mass, whether a star, a human, or a smartphone, attracts other objects through gravity.10. Densityo Definition: The mass of a substance per unit volume; a measure of how tightly packed the particles of an object are.o Sentence: Neutron stars have extremely high density—just a teaspoon of neutron star material would weigh billions of tons.11. Radiationo Definition: The emission or transmission of energy in the form of waves or particles through space or a material medium, such as gamma rays or radio waves.o Sentence: The Black Widow Pulsar emits intense radiation that blasts its nearby brown dwarf companion.12. Celestialo Definition: Relating to the sky or outer space, especially referring to celestial bodies like stars, planets, and galaxies.o Sentence: We are affected by the weak gravitational pull of distant celestial objects, even galaxies millions of light - years away.13. Galaxyo Definition: A large system of stars, gas, dust, and dark matter bound together by gravity; the Milky Way is the galaxy that contains our solar system.o Sentence: The gravitational force between you and the Andromeda Galaxy is surprisingly similar to that between you and a nearby smartphone.14. Pulseo Definition: A short, regular burst of energy, sound, or light.o Sentence: The pulsar sends out regular pulses of radio waves into space.15. Relativityo Definition: The theory developed by Albert Einstein, including special relativity and general relativity, which describes the behavior of matter and energy, especially at high speeds or in strong gravitational fields.o Sentence: Einstein's theory of relativity explains gravity as the curvature of spacetime, a more accurate model than Newtonian mechanics for massive objects.16. Vacuumo Definition: A space that is empty of matter, or where the pressure is much lower than atmospheric pressure; in space, a near - perfect vacuum exists.o Sentence: The vacuum of space does not eliminate gravity—Earth's gravity still acts on the Moon, which is about 400,000 kilometers away.17. Hypotheticalo Definition: Based on a hypothesis; supposed but not necessarily real or proven.o Sentence: In a hypothetical scenario where you dig a tunnel to the center of the Earth, you would experience weightlessness due to balanced gravitational forces.18. Equilibriumo Definition: A state in which opposing forces or influences are balanced, resulting in no net change.o Sentence: At the center of the Earth, gravitational forces from all directions are in equilibrium, so you would float without feeling pulled in any direction.19. Cosmico Definition: Relating to the universe or cosmos, especially as distinct from Earth.o Sentence: Cosmic gravity connects every object in the universe, from the smallest atom to the largest galaxy.20. Fusiono Definition: A nuclear reaction in which atomic nuclei combine to form a heavier nucleus, releasing a large amount of energy; this process powers stars.o Sentence: Unlike stars, brown dwarfs cannot sustain nuclear fusion in their cores because they lack sufficient mass.
