6.11B Gravity

Front

What governs the motion of our solar system?

Back

Gravity governs the motion of our solar system.

Front

What does the gravitational pull of the Sun affect in the planets of our solar system?

Back

The gravitational pull of the Sun affects the speed and shape of the orbit of the planets.

Front

What two factors affect the strength of gravitational pull between two objects?

Back

The strength of gravitational pull is affected by mass and distance.

Front

In which example is the gravitational force of attraction between two objects the smallest?

Back

Example 3 has the smallest gravitational force of attraction.

Front

What would have the smallest gravitational attraction between two masses?

Back

Two objects with very small mass and a large distance between them would have the smallest gravitational attraction.

Front

Define gravity.

Back

Gravity is a force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

How does mass affect gravitational force?

Back

The greater the mass of an object, the stronger its gravitational pull.

Front

How does distance affect gravitational force?

Back

The greater the distance between two objects, the weaker the gravitational pull between them.

Front

What is the relationship between gravity and orbits?

Back

Gravity keeps planets in orbit around the Sun by pulling them towards it while they move forward.

Front

What is the role of the Sun's gravity in the solar system?

Back

The Sun's gravity keeps the planets, asteroids, and comets in orbit around it.
