Space Gravity
100

A force that exists between any two objects that has mass.

Gravity

100

Gravity not only pulls down, but to the _______ of the mass.

Center

100

The force of gravity makes a penguin stick to the ground.

False.  The force of gravity pulls a penguin toward the center of the Earth, NOT sticks it to the ground.

100

Created his theory of gravity after taking a "nap" under a tree.

Isaac Newton.

100

the orbiting of an object around another (caused by gravity).

Revolution.

200

A push or pull that is applied to an object.

Force

200

Gravity applies _______ force to all objects.

equal

200

Weight is the same as Mass.

False.  Weight is affected by the force of gravity.  Mass is the amount of space an object occupies.

200

Known as the father of modern science.

Galileo Galilei

200

Located between Jupiter and Mars

the asteroid belt

300

the force of attraction between all masses

Gravitational Attraction

300

In space, an object in motion will stay in motion until acted upon by an outside

force or object

300

Gravity applies the same force to all objects on Earth, regardless of size.

True.

300

Who said "What goes up, must come down"?

Sir Isaac Newton.

300

The amount of time it takes a planet to circle the sun.

A year

400

The circular or elliptical path of an object as it revolves around another object.

Orbit

400

This force causes heat and will act upon a moving object causing it to slow down.

Friction

400

Earth has more gravity than the sun because it is denser.

False, the Sun has more mass, therefore has more gravity.

400

The _______ of the objects in space is what draws them together.

mass.

400

The cause of an object's increased speed is a force that has acted on it.....

in the same direction it is moving.

500

a force that is caused by air.  The force acts in opposite direction to an object moving through the air.

Air resistance.

500

If an object moves and no FORCE affects it, it will

keep going!

500

Due to the difference in mass and gravitational attraction, the earth with less gravity orbits the Sun because it has greater gravity.

True.

500

Was imprisoned for his ideas on the Universe.

Galileo

500

If you can see it, touch it, weigh it, it has....

mass.
