Gravity

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

True or False: The planets get larger as they move farther from the Sun.

Back

False

Front

What happens to gravitational force as mass increases?

Back

The gravitational force increases.

Front

What remains constant as a person moves around the universe?

Back

Mass stays constant.

Front

What changes as a person moves around the universe?

Back

Weight changes.

Front

What two factors affect the magnitude of the force of gravity between two objects?

Back

Mass and distance.

Front

What is the edge of a black hole called?

Back

The Event Horizon.

Front

What is the relationship between mass and weight?

Back

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

Front

How does distance affect gravitational force?

Back

As the distance between two objects increases, the gravitational force between them decreases.

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 the centers of the two masses.
