6.11B Gravity

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

Why do planets orbit the Sun?

Back

Planets orbit the Sun because it is the celestial body with the greatest mass, creating a strong gravitational pull.

Front

What governs the motion of our solar system?

Back

Gravity governs the motion of our solar system.

Front

How does distance affect gravitational attraction?

Back

The gravitational attraction between two objects decreases as the distance between them increases.

Front

What happens to gravitational force if the mass of an object increases?

Back

If the mass of an object increases, the gravitational force it exerts also increases.

Front

What is a high tide?

Back

A high tide is when the water level in the ocean rises due to the gravitational pull of the Moon and the Sun.

Front

How many points on Earth experience high tides at the same time?

Back

At any given time, two points on Earth experience high tides.

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 an example of gravitational attraction?

Back

An example of gravitational attraction is the pull between the Earth and the Moon.

Front

What effect does the Sun's gravity have on the planets?

Back

The Sun's gravity keeps the planets in orbit around it.
