Gravity Practice

Which of these objects exerts a gravitational pull? (Click all that apply.)

• The Sun

• The Earth

• The Moon

• your pencil

• a fly

What is something that has a larger gravitational field than the Earth?

• my pencil

• a fly

• Mars

• the moon

• the Sun

WHY does the Sun create a LARGER gravitational field than the Earth?

• The Sun has more magnetism than the Earth and this creates a larger gravitational field

• The Sun is hotter than the Earth and this creates a larger gravitational field.

• No one knows why

• The Sun has more MASS than the Earth, so it creates a larger gravitational field than the earth does.

When objects are FARTHER APART, is the force of gravity between them STRONGER or WEAKER?

• When objects are farther apart, the gravity between the objects is STRONGER.

• When objects are farther apart, the gravity between them is WEAKER.

What happens to objects when they get closer to the Moon?

• They float away into space

• They get pulled toward the Moon

• They stay in the same place

• They get pulled toward the Earth

What is the force that keeps objects from flying off the surface of the Earth?

• Friction

• Magnetism

• Gravity

• Inertia

The gravitational attraction between two objects would increase if both masses are –

• increased, and the distance between them is increased.

• increased, and the distance between them is decreased.

• decreased, and the distance between them is decreased.

• decreased, and the distance between them is increased.

Why do planets orbit the Sun?

• The Sun is the only celestial object that has a gravitational pull.

• The Sun’s chemical composition makes it attract planets.

• Only celestial bodies that emit light, like the Sun, can be at the center of an orbit.

• The Sun is the most massive object in our solar system, so it exerts the greatest gravitational pull.

As distance between two objects increases, the pull of gravity 

• increases.

• decreases.

• stays the same.

• has no effect.

Why are we pulled to Earth's center and NOT the sun's?

• The sun is very LARGE

• The sun is very FAR AWAY

• Earth has a STRONGER GRAVITY than the sun

• Earth ORBITS around the sun
