Gravity in Our Solar System

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

Which has more mass, Earth or the Moon?

Back

Earth has more mass than the Moon.

Front

How often do the high tides change to low tides daily?

Back

High tides change to low tides every 6 hours and 12 minutes.

Front

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

Back

The two factors are mass and distance.

Front

What is mass?

Back

Mass is the amount of matter in an object.

Front

What is a spring tide?

Back

A spring tide occurs when the sun, Earth, and the moon are nearly in a line, resulting in higher high tides and lower low tides.

Front

What is a neap tide?

Back

A neap tide occurs when the sun and moon are at right angles relative to the Earth, resulting in lower high tides and higher low tides.

Front

How does distance affect gravity?

Back

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

Front

What is the relationship between mass and gravity?

Back

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

Front

What is the gravitational force on Earth?

Back

The gravitational force on Earth is approximately 9.81 m/s².
