Unit 2: Earth and the Solar System

Which is the correct order in regards to their distance from the sun from least to greatest?

___________ is a gravitational force exerted on an object by a planet or moon.

Half of the year the Earth's North Pole is tilted towards the sun & the other half it is tilted away from the sun.

Our entire solar system orbits around which galaxy?

How long does it take for the moon to orbit the earth?

Engineers use scientific knowledge and mathematics to solve problems by creating new technologies.

Scientists are trying to answer a question, while engineers are trying to solve a problem.

Our solar system is located near the edge of the Milky Way Galaxy.

Momentum is an objects speed multiplied by its mass.

How many planets are in our solar system?

Technology is anything that people have modified from the natural world to meet their needs and wants.

Gravitational field is the area around 1 object where another object will feel the gravitational force of the 1st object

Drag is a force that transfers motion out of an energy system by causing some of the energy to change into heat.

There is constant motion in the universe because of gravity's attractive pull.

The acceleration due to gravity on Jupiter is?

Why does Neptune experience seasons?

The gravitational force exerted on an object by a planet or moon is called weight.

Planets that are further away from the sun experience a stronger pull of the sun's gravity than planets that are closer.

A solar system is a collection of planets and other objects that orbit a sun.

A single season on Neptune can last for more than 40 years, why is this?

The more massive an object is, the more gravity will pull on other objects and cause them to move.

A _______ is a star at the center of a solar system.

Rockets are designed to move because of action-reaction forces (Newton's 3rd law of Motion)

The acceleration due to gravity on the moon is?

What is the role of gravity in causing motion?

A galaxy is a large cluster of stars held together by gravity and separated by unimaginable distances of space.

Newton's second law says that the greater the thrust (force) the greater the acceleration?

When a rocket is more massive it needs more thrust (force) to reach the same acceleration as a rocket with less mass.

When a rocket clears Earth's gravitational field, it would continue to move in a straight line because of inertia.

We always see the same side of the moon because the moon orbits Earth at the same rate it rotates on its axis.

Why do we have seasons?

The Earth being tilted at 23.5 degrees creates what?

Earth is tilted _________ degrees on its axis?

What criteria need(s) to be met in order to considered a planet?

An eclipse occurs when one object in the solar system moves into the shadow of another object.

A meteor crashes into a satellite, damaging the satellite. The damage is caused by which of the following?

About 500,000 pieces of space debris orbit the Earth, why?

Do you have gravity?

The engineering process is similar to the scientific process but it differs because each has a different goal.

The sun is the most massive object in our solar system?

There is ___________ gravity on the space station compared to Earth?

The moon emits its own light.

Terrestrial planets include all of the following except?

How long does it take for the Earth to orbit the sun?

The acceleration due to gravity on Earth is?

The asteroid belt is between Jupiter and Saturn.

______ have similar properties because they are the four rocky planets in the inner solar system.

A __________ is a period of time characterized by specific weather patterns and by the length of day and night.

Gas giants include all of the following except

When the Earth's North Pole is tilted towards the sun, the rays have a high angle and intensity when hitting Earth.

The gas giants rotate (spin) much faster than any of the terrestrial planets.

What is the force of attraction between all matter?

Our solar system is in motion within _________, which is a large cluster of stars held together by gravity.

How would you describe the strength of the sun's gravity in the solar system?

Orbit means to

Why does Jupiter have the greatest amount of acceleration due to gravity in our solar system?
