100
The force air exerts on a moving object.
What is air resistance?
100
Every object in the universe exerts a force on every other object.
What is gravity?
100
The force equation.
What is force equals mass times acceleration?
100
This is also called action-reaction.
What is Newton's Third Law of Motion?
100
Russia or former Soviet Union.
Who launched the first artificial satellite?
200
The highest velocity that will be reached by a falling object.
What is terminal velocity?
200
The force that opposes motion between two surfaces that are touching each other.
What is friction?
200
A net force acting on an object causes the object to accelerate in the direction of the force.
What is Newton's Second Law?
200
This is how momentum is calculated.
What is momentum equals mass times velocity?
200
An artificial satellite whose orbit matches the speed of the movement of the Earth.
What is a geostationary satellite?
300
Acceleration toward the center of a curved or circular path.
What is centripetal acceleration?
300
The measure of the force of gravity.
What is weight?
300
9.8 meters per second squared
What is acceleration due to gravity?
300
The game of pool is one example of this.
What is an example of conservation of momentum?
300
Long periods in space.
What causes health problems such as bone and muscle deterioration?
400
Human-made devices that orbit Earth for a specific purpose?
What is an artificial satellite?
400
A force on an object that always changes the velocity of the object.
What is net force?
400
When an object is influenced only by gravity.
What is free-fall?
400
This causes circular motion.
What is centripetal forces?
400
This doesn't change when an astronaut is in space?
What is mass?
500
A property a moving object has because of it mass and velocity.
What is momentum?
500
An object moving at a constant velocity keeps moving at that velocity unless a net force acts on it.
What is Newton's First Law of Motion?
500
This is why a projectile follows a curved path.
What is Earth's gravitational pull and projectile's own inertia?
500
This is why a full-sized fire truck has more momentum than a toy fire truck.
What is greater mass?
500
This causes an artificial satellite's orbit to lose energy and allow Earth's gravity to pull it down.
What is air resistance?
