Flashcard: Escaping a Black Hole

Front

What is a gravitational field?

Back

The area where an object exerts gravity.

Front

What is a black hole?

Back

A collapsed star.

Front

What happens to light near a black hole?

Back

Light cannot escape due to the black hole's strong gravitational force.

Front

What is the event horizon of a black hole?

Back

The boundary around a black hole beyond which nothing can escape.

Front

How does gravity affect time near a black hole?

Back

Time slows down as you approach a black hole due to its strong gravitational field.

Front

What is the difference between a black hole and a neutron star?

Back

A black hole is formed from a collapsed star with gravity so strong that not even light can escape, while a neutron star is a dense remnant of a supernova explosion.

Front

What is the concept of 'spaghettification'?

Back

The stretching and compressing of objects into long thin shapes due to extreme gravitational forces near a black hole.

Front

What is a singularity in the context of black holes?

Back

A point at the center of a black hole where density is thought to be infinite and the laws of physics as we know them break down.

Front

What is the role of mass in a black hole's gravitational pull?

Back

The greater the mass of a black hole, the stronger its gravitational pull.

Front

What is the 'slingshot effect' in space travel?

Back

Using the gravity of a planet or star to gain speed and change direction without using fuel.
