Black Holes, Relativity/Spacetime, Circular Motion, ULOG

Front

What is a black hole?

Back

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

Front

What is the principle of relativity?

Back

The laws of physics are the same for all observers, regardless of their relative motion.

Front

Define spacetime.

Back

A four-dimensional continuum that combines the three dimensions of space with the dimension of time.

Front

What is circular motion?

Back

Motion of an object in a circular path, where the object is constantly changing direction.

Front

What is gravitational force?

Back

The attractive force between two masses, which depends on their masses and the distance between them.

Front

How does mass affect gravitational force?

Back

Gravitational force increases with greater mass and decreases with greater distance.

Front

What is the formula for gravitational force?

Back

F = G * (m1 * m2) / r^2, where F is the gravitational force, G is the gravitational constant, m1 and m2 are the masses, and r is the distance between their centers.

Front

What happens to the gravitational force if the distance is doubled?

Back

The gravitational force becomes one-fourth of its original value.

Front

What is the significance of Earth's rotation period?

Back

Earth rotates on its axis approximately every 24 hours, which defines the length of a day.

Front

What is the effect of distance on the force between charged objects?

Back

The force decreases as the distance between charged objects increases, following an inverse square law.
