Intro to Energy
To be able to cause change.
What is energy?
The total kinetic energy of something.
What is thermal energy?
How much air is pushing down on something.
What is air pressure?
The movement of air caused by differences in air pressure.
What is wind?
The energy of movement.
What is kinetic energy?
The average kinetic energy of something.
What is temperature?
78% of this element is in the atmosphere.
What is nitrogen?
The curving path of an object due to the rotation of the Earth.
What is the Coriolis Effect?
Energy due to chemical composition or position.
What is potential energy?
Heat is measured in joules and this measurement.
What are calories?
The mixture of gases that surround the Earth.
What is the atmosphere?
Narrow belts of wind that blow from west to east.
What are jet streams?
When energy changes from one form to another.
What is energy transformation?
Conduction, convection, and radiation are all examples of this.
What is heat transfer?
The energy transferred between objects with different temperatures.
What is heat energy?
Winds that move over short distances.
What are local winds?
The sum of an object's kinetic and potential energy.
What is mechanical energy?
One calorie raises an object's temperature by this much.
What is 1 Co?
This occurs when an object's volume changes because of a change in temperature.
What is thermal expansion?
Winds that blow between 30o latitude and the equator in both hemispheres.
What are trade winds?
