Front

What is the force that pulls all objects with mass toward one another?

Back

Gravity

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.

Front

Which planets are known as terrestrial planets?

Back

The inner planets: Mercury, Venus, Earth, and Mars.

Front

What are Jovian planets?

Back

The outer planets: Jupiter, Saturn, Uranus, and Neptune.

Front

What has more gravitational force than any of the planets in the solar system?

Back

The Sun.

Front

How does gravity affect objects on the Moon compared to Earth?

Back

Objects weigh less on the Moon due to its weaker gravitational pull.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the gravitational force between two objects dependent on?

Back

The mass of the objects and the distance between them.

Front

What is the role of gravity in the solar system?

Back

Gravity keeps planets in orbit around the Sun and moons in orbit around planets.
