7.10B Gravity and the Solar System

Front

What is gravity?

Back

A type of force that attracts two objects towards each other.

Front

Which system has the greater gravitational attraction between two objects?

Back

The system with the larger mass has greater gravitational attraction.

Front

What force pulled the solar system together out of a cloud of gas and dust?

Back

Gravity.

Front

As the mass of interacting objects decreases, what happens to gravity?

Back

Gravity decreases.

Front

According to Sir Isaac Newton, what two factors does gravity depend on?

Back

Mass and distance.

Front

What is the relationship between mass and gravitational force?

Back

Greater mass results in a stronger gravitational force.

Front

How does distance affect gravitational attraction?

Back

As distance increases, gravitational attraction 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.

Front

What is the gravitational force between two objects with equal mass and distance?

Back

The gravitational force is the same for both objects.

Front

What happens to gravity if the distance between two objects is halved?

Back

Gravity increases.
