How does gravity differ on the moon VS earth?

the moon's gravity is about 1/6 of earth's.

100

This type of force is directed toward the center of a circular path, keeping an object moving in a circle.

what is centripetal force?

100

These two factors work together to keep Earth in orbit around the Sun.

what are gravity and inertia?

100

Often called "dirty snowballs," comets are composed of these three main ingredients: dust, rock, and this frozen substance.

what is ice?

100

in Genesis 1, this was created on Day One before the sun, moon, and stars.

what is light?

200

Why do astronauts feel weightless?

they are in a constant state of free fall/orbit

200

This is the direction of the acceleration for an object moving in a circle at a constant speed.

what is toward the center?

200

This term describes the path, often slightly elliptical, that a planet takes around the Sun.

what is orbit?

200

This most famous periodic comet is visible from Earth roughly every 76 years, last appearing in 1986.

what is Halley's comet?

200

These celestial bodies were created on Day Four to mark days, years, and seasons.  

what are the sun, moon, and stars?

300

This is defined as the measurement of the force of gravity on an object.

what is weight?

300

This quantity, representing resistance to changes in motion, causes a car passenger to feel like they are being pushed outward in a sharp turn.

what is inertia?

300

Because the sun has the greatest mass, it exerts the strongest gravitational pull, followed by this planet.

what is jupiter?

300

Comets are remnants from the formation of the solar system, making them approximately this many billion years old.

what is 4.6 billion years?

300

The Bible states that this, rather than a molten ball of rock, was the initial state of the Earth.

what is covered by water?

400

According to Newton, this is the reason why the moon remains in the vicinity of the Earth.

what is gravitational force? 

400

This force opposes motion between two surfaces that are touching.

what is friction?

400

Because of these, a planet travels faster in its orbit when it is closer to the Sun and slower when it is farther away.

What are Kepler's Laws?

400

Unlike the near-circular orbits of planets, comets typically follow this type of elongated, egg-shaped path.

What is an elliptical orbit?


400

This miraculous event in Matthew 2, which guided the Magi, is often cited as a unique celestial phenomenon.

what is the Star of Bethlehem?

500

he replaced newtons gravitational theory with the theory of general relativity

who is albert einstine?

500

The acceleration of an object in uniform circular motion does not depend on this property of the object.

what is mass?

500

The gravitational pull of the Sun is so strong that it contains this percentage of the total mass of the entire solar system.

what is 99.86%?

500

The annual Perseid meteor shower is caused by Earth passing through debris left behind by this comet.

what is comet Swift-Tuttle?

500

 Exodus 20:11 states that God created the heavens, earth, sea, and all that is in them within this timeframe.

what is 6 days?
