turn up the heat
In the U.S. this is the most common temperature scale used.
What is the Fahrenheit scale?
This person built the first steam powered machine.
What is Thomas Savery?
By using this, you can tell if an object is in motion.
What is a reference point?
This person created the three laws of motion.
What is Sir Isaac Newton?
Most matter exists in this amount of states.
What is three?
Some people used sand to show this at the end of their roller coasters.
What is inertia?
This only moves in one direction.
What is heat?
This person gets the most credit for the steam engine.
What is James Watt?
You know what this is when you know the speed and direction of an object's motion.
What is velocity?
These are described not only by how strong they are, but also by the direction in which they act.
What is forces?
These have a definite volume but not a fixed shape.
What is liquids?
The first things resembling roller coasters were invented by these people.
What is Russians?
Wood, wool, straw, paper, cork, and gases are examples of this.
What is insulators?
These two people were the creators of The Rocket.
What is George and Robert Stephenson?
When the slope on a graph representing an objects motion is horizontal, this means that the object is doing this.
What is not moving?
The amount of this an object has depends on its mass.
What is inertia?
The state of a substance depends on the amount of this it possesses.
What is thermal energy?
When the marble is at the top of the first slope it has this type of energy.
What is potential energy?
This is a circular motion that is cause by convection.
What is a convection current?
What is Richard Trevithick?
If a car turns a corner at a constant speed he is still doing this.
What is accelerating?
When the value for force increases, the value for this also increases.
What is acceleration?
This is what happens when vaporization occurs under the surface of a liquid.
What is boiling?
This is the force that causes the marble to fall down the slopes on the tracks.
What is gravity?
This is the amount of energy required to raise the temperature of 1 kilogram of a substance by 1 kelvin.
What is specific heat?
He invented the aeolipile and or "wind ball".
What is Hero of Alexandria.
A decrease in acceleration is sometimes called this and that.
What is deceleration and negative acceleration?
As the velocity of a falling object increases, this also increases until it is equal to the force of gravity.
What is air resistance?
This is the change of state from a solid to a gas.
What is sublimation?
When the track turns and bends, the marble still hangs onto the track because of this.
What is centripetal force?
