These are two examples of Centrifugal Force.
What are Artificial Gravity and the Gravitron. (Other valid examples are accepted as well)?
200
The numerical constant tells us that gravity is a very weak force. (Correct response must include full name)
What is The Universal Gravitational Constant, G?
200
This Newton Law of Motion supports the idea that an object will always continue in a straight line path
What is Newton's First Law of Motion (Or Law of Inertia)..."An object in motion..."
300
The number of rotations or revolutions per unit of time
What is Frequency?
300
An object in circular motion follows this path if the centripetal force is removed.
What is straight line path OR tangent to the direction of motion?
300
By achieving this centripetal acceleration, you can achieve artificial gravity in a rotating system.
What is 9.8 m/s^2 or 10 m/s^2
300
You can decrease the force between two objects by increasing this variable.
What is distance?
300
Isaac Newton created this branch of mathematics to calculate the motion of the falling moon
What is Calculus?
400
Speed of something moving along a circular path
What is Tangential Speed?
400
Three people riding a merry-go-round travel at the same RPM. The travel at the same ___________ speed.
What is Rotational Speed?
400
These are some examples of the dangers astronauts face due to weightlessness in space.

What is Newton's Third Law of Motion (Every object attracts....)
500
Any force that causes an object to follow a circular path
What is Centripetal Force?
500
Increasing these 2 variables will increase the tangential speed of an object.
