17 de dic. de 2020 · La gravedad es lo que hace que los planetas entren en órbita alrededor de las estrellas--como la Tierra que está en órbita alrededor de nuestra estrella, el Sol. La gravedad es lo que hace que las estrellas se junten entre sí para formar enormes galaxias giratorias.

Why do you land on the ground when you jump up instead of floating off into space? Why do things fall down when you throw them or drop them? The answer is gravity: an invisible force that pulls objects toward each other. Earth's gravity is what keeps you on the ground and what makes things fall. An animation of gravity at work. Albert Einstein desc...
Gravity is what holds the planets in orbitaround the sun and what keeps the moon in orbit around Earth. The gravitational pull of the moon pulls the seas towards it, causing the ocean tides. Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light. Albert Einstein ...
Gravity is very important to us. We could not live on Earth without it. The sun's gravity keeps Earth in orbit around it, keeping us at a comfortable distance to enjoy the sun's light and warmth. It holds down our atmosphere and the air we need to breathe. Gravity is what holds our world together. However, gravity isn’t the same everywhere on Earth...
Gravity is measured by the acceleration that it gives to freely falling objects. At Earth ’s surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second.
In physics, gravity (from Latin gravitas 'weight' [1]) is a fundamental interaction which causes mutual attraction between all things that have mass. Gravity is, by far, the weakest of the four fundamental interactions, approximately 10 38 times weaker than the strong interaction, 10 36 times weaker than the electromagnetic force and 10 29 ...
We understand that gravity is a purely attractive force – it can only pull, never push – and that it is generated by any object with mass. But humankind has been trying to answer this question for thousands of years.
Mueve el sol, la tierra, la luna y la estación espacial para ver cómo afecta sus fuerzas gravitatorias y trayectorias orbitales. ¡Visualiza los tamaños y las distancias entre los diferentes cuerpos celestes y desactiva la gravedad para ver lo que pasaría sin estar con gravedad!
30 de jul. de 2023 · Gravity: A tool of discovery. The modern description of gravity so accurately predicts how masses interact that it has become a guide for cosmic discoveries.
