Components of the Universe

Front

What are the main components of the universe?

Back

The main components of the universe include galaxies, stars, planets, moons, asteroids, comets, and dark matter.

Front

What is gravity?

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; an object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is an orbit?

Back

An orbit is the curved path that an object takes around a star, planet, or moon due to the gravitational force.

Front

What keeps the planets in orbit around the sun?

Back

The gravitational force exerted by the sun keeps the planets in orbit around it.

Front

What is a galaxy?

Back

A galaxy is a massive system that consists of stars, stellar remnants, interstellar gas, dust, and dark matter, bound together by gravity.

Front

What is the difference between a planet and a star?

Back

A planet is a celestial body that orbits a star and does not produce its own light, while a star is a massive celestial body that generates light and heat through nuclear fusion.

Front

What is dark matter?

Back

Dark matter is a form of matter that does not emit light or energy, making it invisible and detectable only through its gravitational effects on visible matter.

Front

What is the solar system?

Back

The solar system is a collection of celestial bodies, including the sun, planets, moons, asteroids, and comets, that are bound by gravity.

Front

What is the role of the sun in the solar system?

Back

The sun is the central star of the solar system, providing light and heat, and its gravitational force keeps the planets in orbit.
