The Sun is a star.

All objects in our solar system revolve around the Earth.

The star that is in the center of our solar system is the Sun.

 The Sun is the largest planet in our solar system.

What is the largest planet in our Solar System?

A rock from space that lands on Earth's surface

A small rock located in space and is made from a piece of asteroid that broke off.

A rock from space that entered Earth’s atmosphere. Also known as a shooting star or falling star.

A large rock that is smaller than planets.

Planets, moons, stars, comets, asteroids, and meteoroids.

Also known as moons and revolve around planets

Made of ice, dust, and gas. Have a head and a tail.

is measured with a spring scale and its units are Newtons (N)

is measured with a triple beam balance and its units are grams

is affected by the force of gravity

 is the amount of matter or “stuff” inside of an object.

does NOT change, even when gravity changes.

changes by location

is the force of gravity pulling on an object

can be found by multiplying mass times gravity

What would happen to Michael Jordan’s  mass if he went to the moon.

What would happen to Michael Jordan’s  weight if he went to the moon.

is the attraction between every object in the universe

is an object’s resistance to any change in motion.

causes an object at rest to stay at rest and an object in motion to stay in motion unless acted on by an outside force

causes the forward motion of planets

The Sun’s _____________ keeps planets in orbit.

Planets are kept in orbit around the Sun due to the Sun’s gravitational pull and inertia.

If there was no gravity between the planets and the Sun, inertia would cause the planets to travel off into space in a straight line.

Objects on Earth are attracted to the core’s gravitational pull.

The greater the mass of a planet, the greater its gravitational pull.

As distance increases between objects, gravity increases.
