Galaxies and Gravity

Front

What force keeps the planets held in their orbit?

Back

Gravitational force is the force that keeps planets in their orbit around the sun.

Front

What is true about the dark areas of the night sky?

Back

Objects in the dark areas of the sky are too far to be seen.

Front

If 2 planets of the same mass are in space and A is closer to the sun while B is farther away from the sun, which one will have a stronger gravitational field/force?

Back

Planet A will have a stronger gravitational force because it is closer to the sun.

Front

Gravity is the force objects put on each other because of their ____________.

Back

Mass. Gravity is dependent on the mass of the objects.

Front

True or False: Galaxies are moving toward one another and may collide in the future.

Back

True. Galaxies are indeed moving toward each other and may collide.

Front

What is a galaxy?

Back

A galaxy is a massive system that consists of stars, star clusters, dust, gas, and dark matter, all bound together by gravity.

Front

What is the Milky Way?

Back

The Milky Way is the galaxy that contains our solar system.

Front

What is a black hole?

Back

A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape from it.

Front

What is the role of gravity in the universe?

Back

Gravity is the force that holds galaxies, stars, and planets together and governs their movements.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
