Gravity in the Solar System

Front

What is gravity?

Back

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

Front

What is the speed of Earth's orbit around the sun?

Back

Earth moves around the sun at a speed of approximately 30 km/s.

Front

What is a scale model?

Back

A scale model is a physical representation of an object that maintains accurate relationships between its dimensions.

Front

Why do planets have a nearly spherical shape?

Back

Planets are nearly spherical due to gravitational forces pulling matter toward their centers.

Front

What is the strongest gravitational force?

Back

The gravitational force on a baseball from Earth is the strongest compared to other nearby objects.

Front

What is an astronomical unit (AU)?

Back

An astronomical unit (AU) is a unit of measurement equal to the average distance from the Earth to the Sun, approximately 93 million miles.

Front

How does gravity affect the motion of planets?

Back

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

Front

What role does gravity play in the formation of celestial bodies?

Back

Gravity causes gas and dust in space to clump together, forming stars, planets, and other celestial bodies.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force between two objects increases with greater mass and decreases with greater distance.

Front

How does the distance between two objects affect gravitational force?

Back

The gravitational force decreases as the distance between two objects increases.
