Microgravity Questions: Trivia Quiz!

1. Gravitation is the attraction of objects due to their masses

True

False

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

Explanation

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

2. What does "Freefall" mean in this class?

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

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

Jumping off of something without having to pay for it.

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

"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.

3. YOU create an attractive force in our universe?

True

False

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

4. What is Microgravity?

A really really really really tiny piece of gravity

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

Too tiny to know the answer

No gravity at all.

Microgravity is an environment in which the apparent weight of a system is small compared to its actual weight due to gravity.

Explanation

Microgravity is an environment in which the apparent weight of a system is small compared to its actual weight due to gravity.

5. You can simulate microgravity here on earth where we have regular gravity.

True

False

We can simulate microgravity here on earth! We're going to do it in class very soon!

Explanation

We can simulate microgravity here on earth! We're going to do it in class very soon!

6. Newton's first law says:

Force = Mass X Acceleration

The cowboys are the greatest football team ever!

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

For every action there is an equal and opposite reaction

You're going to need to know these forward, backward, upside down, and sideways on the ship!

Explanation

You're going to need to know these forward, backward, upside down, and sideways on the ship!

7. What is the meaning of the word "Orbit"

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

To float near an object in space

To be pulled around by the gravity of an object

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

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...

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...

8. Newton's third law says...

Force = Mass X Acceleration

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

For every action, there is an equal and opposite reaction

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!

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!

9. Newton's second law says...

F = Mass X Acceleration

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

For every action there is an equal and opposite reaction

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

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!

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!

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

Faster than on Mars

9.8 m^2

28 Mph

I dunno... Fast?

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....
