### What is Microgravity?

• A.

A really really really really tiny piece of gravity

• B.

An environment where weight is a lot less than what it would be in regular gravity

• C.

Too tiny to know the answer

• D.

No gravity at all.

B. An environment where weight is a lot less than what it would be in regular gravity
Explanation
Microgravity is an environment in which the apparent weight of a system is small compared to its actual weight due to gravity.

### Newton's first law says:

• A.

Force = Mass X Acceleration

• B.

The cowboys are the greatest football team ever!

• C.

An object in motion stays in motion or at rest until acted on by another force

• D.

For every action there is an equal and opposite reaction

C. An object in motion stays in motion or at rest until acted on by another force
Explanation
You're going to need to know these forward, backward, upside down, and sideways on the ship!

### Newton's second law says...

• A.

F = Mass X Acceleration

• B.

An object in motion or at rest will stay in motion or at rest, until a force acts on it.

• C.

For every action there is an equal and opposite reaction

• D.

YOU HAVE TO COME TO THE CUBS FIRST FOOTBALL GAME ON THE 29th! GO CUBS!

A. F = Mass X Acceleration
Explanation
Man I hope you're getting these right! And, if you go to the Cubs game and take a selfie of yourself and the field I'll give you some bonus points!

### Newton's third law says...

• A.

Force = Mass X Acceleration

• B.

An object at rest will stay at rest until moved by something, and an object in motion will stay in motion until stopped by something.

• C.

If a tree falls in the forest and nobody is around, then it didn't make a sound anyway.

• D.

For every action, there is an equal and opposite reaction

D. For every action, there is an equal and opposite reaction
Explanation
No seriously, you will need to know all of these by heart. And I'm SERIOUS about getting those bonus points if come to the game and take a selfie! Wear Green and/or Orange!

### What is the meaning of the word "Orbit"

• A.

The curved path of an object or spacecraft around a star, planet, or moon

• B.

To float near an object in space

• C.

To be pulled around by the gravity of an object

• D.

To get an attitude with someone you really don't like

A. The curved path of an object or spacecraft around a star, planet, or moon
Explanation
Orbit is something we're going to have to figure out before we get to mars... if we don't we'll crash into the planet and die. Not fun...

### What does "Freefall" mean in this class?

• A.

What my grade will do if I don't pay attention.

• B.

Letting someone get some some of your drink without touching their mouth on it.

• C.

Jumping off of something without having to pay for it.

• D.

Falling in a gravitational field where the acceleration is the same as that due to gravity alone.

D. Falling in a gravitational field where the acceleration is the same as that due to gravity alone.
Explanation
"Freefall" in this class refers to falling in a gravitational field where the acceleration is the same as that due to gravity alone. It does not refer to the other options mentioned in the question such as the consequence of not paying attention, sharing a drink, or jumping off something without paying. The correct answer specifically relates to the physics concept of freefall, where an object is only influenced by the force of gravity and experiences an acceleration equal to that of gravity.

### The acceleration of Earth's gravity is...

• A.

Faster than on Mars

• B.

9.8 m^2

• C.

28 Mph

• D.

I dunno... Fast?

B. 9.8 m^2
Explanation
9.8 m^2 means 9.8 meters per second and then doubled after every second. 1st second = 9.8 m/s. 2nd second = 19.6 m/s. 3rd second = 29.8 m/s! You're speeding up every second that you are falling! I hope you have a parachute....

### Gravitation is the attraction of objects due to their masses

• A.

True

• B.

False

A. True
Explanation
This is true. The more mass something has... the more attracting force it has to objects around it.

Rate this question:

• 10.

### YOU create an attractive force in our universe?

• A.

True

• B.

False

A. True
Explanation
Everything in our universe creates an attracting force. In other words... YOU HAVE GRAVITY.
