Kinetic Friction
What is friction that opposes motion once the motion has already started?
100
His teachings were the basis for Roman Catholic philosophy.
Who is Aristotle?
100
Newton's First Law
What is an object in motion or at rest tends to stay in motion or at rest unless acted upon by an outside force?
100
Newton's 2nd Law
What is when an object is acted on by one or more outside forces, the total force is equal to the mass of the object times the resulting acceleration. (TF = mass x acceleration)
100

Newton's 3rd Law

What is for every action, there is an equal and opposite reaction?

200
inertia
What is the tendency of an object to resist changes in its velocity?
200

 He was knighted by Queen Anne in 1705 for all of his accomplishments in the field of science.

Who is Sir Isaac Newton?

200

DAILY DOUBLE!!! In one of our experiments, this kept spinning even after it was physically stopped, due to inertia.

What is the raw egg?

200
kg times m over seconds squared
What is Newton?
200
This happens when you fire a gun because it is the equal and opposite reaction to the pressure & heat acting on the bullet.
What is kick?
300

DAILY DOUBLE!!!! friction

What is a force that opposes motion, resulting from the contact of two surfaces?

300
He believed that by studying science, he was actually learning about God.
Who is Sir Isaac Newton?
300
The problem with Aristotle's thinking with the penny sliding with the card as it was pulled across the glass jar.
What is objects at rest want to stay at rest, so since no force was acting on the penny, it should have stayed where it was and dropped into the glass jar.
300

DAILY DOUBLE!!! A vector quantity whose magnitude is usually measured in Newtons.

What is force?

300
An ice skater stands on the ice in his skates. He is holding a ball. Assuming there is no friction, what will happen to the ice skater if he suddenly throws the ball hard to the east?
What is He will move to the west.
400
Static friction
What is friction that opposes the initiation of motion?
400

DAILY DOUBLE!!! He believed that objects at rest want to stay at rest, and this is why everything in motion eventually slows down and stops.

Who is Aristotle?

400
Spacecraft launched in 1977 which are still traveling at 38,000 mph up in space with no fuel left to burn.
What are Voyager 1 and Voyager 2?
400
When something is stationary relative to the surface upon which it sits, the frictional force is large and the object is hard to move.
What is static friction?
400
A child pushes against a St. Bernard dog, trying to move him. The dog remains stubbornly unmoved. Something exerts the equal and opposite force which Newton's 3rd Law of Motion says must happen in response to the child's push.
What is the St. Bernard dog.
500
The motion of an object when it is falling solely under the influence of gravity.
What is free fall?
500
The three scientists who were eventually able to change scientific thought about certain things & dispose of Aristotle's mistakes.
Who are Copernicus, Galileo, & Newton?
500
A person jumping from an airplane & wishing to land on a hill cleared of trees will jump out of the plane before he can even see the hill, as they are approaching the hill, or when they are directly over the hill.
What is "as they are approaching the hill".
500

A box is moving at a constant velocity, it is neither speeding up nor slowing down. What is it's rate of acceleration?

What is 0?
