Gravity and Space review

Front

What is gravitational attraction?

Back

Gravitational attraction is the force that pulls two objects toward each other, proportional to their masses and inversely proportional to the square of the distance between their centers.

Front

Which planet has the strongest gravitational attraction with a star?

Back

The planet closest to the star will generally have the strongest gravitational attraction due to its proximity.

Front

What separates the inner and outer planets in our solar system?

Back

The asteroid belt separates the inner planets (Mercury, Venus, Earth, Mars) from the outer planets (Jupiter, Saturn, Uranus, Neptune).

Front

What are the inner planets of our solar system?

Back

The inner planets are Mercury, Venus, Earth, and Mars, which are characterized by their rocky surfaces.

Front

What is the characteristic of the surfaces of inner planets?

Back

Inner planets are considered to have rocky surfaces.

Front

What happens to the speed of falling objects in a vacuum?

Back

In a vacuum, all objects fall at the same speed regardless of their mass.

Front

What is the relationship between a planet's distance from the sun and the length of its year?

Back

As a planet gets further from the sun, the length of its year increases due to a longer orbital path.

Front

What is the asteroid belt?

Back

The asteroid belt is a region of space between the orbits of Mars and Jupiter that contains numerous rocky bodies.

Front

How does gravity affect the motion of planets?

Back

Gravity keeps planets in orbit around stars and affects their speed and trajectory.

Front

What is the significance of the distance between a planet and its star?

Back

The distance affects the gravitational attraction and the length of the planet's year.
