States of matter and phase changes
A solid becoming a gas without first being a liquid
What is sublimation?
The energy of movement
What is kinetic energy?
A push or a pull
What is force?
A form of energy resulting from a difference in charges
What is electricity?
This describes how water condenses from the clouds as precipitation, moves to bodies of water as run off, and evaporates back into the clouds
What is the water cycle?
A state of matter which has a defined shape and volume
What is a solid?
Energy related to structure or position
What is potential energy?
A speed with a direction, such as 5 miles/hour south
The negatively charged particle which moves to generate electric current
What is an electron?
This describes how earth's surface gets its energy from the sun even though the sun is millions of miles away
What is electromagnetic radiation?
One of the three phase changes which results from the removal of energy (heat) from matter
What are freezing, condensation, and deposition?
According to the law of conservation of energy, energy cannot be created or this
What is destroyed?
The tendency of objects to stay in motion if they are moving or resist moving if they are not moving yet
What is inertia?
Charges which attract each other in electric or magnetic fields are this
What is opposite?
This form of heat transfer is how water circulates to cause deep ocean currents and how air circulates to cause the global winds
What is convection?
The state of matter in which atoms or molecules are far apart and move freely
What is a gas
Temperature, velocity, and electromagnetic radiation are all related to this kind of energy.
What is kinetic energy?
Forces such as electromagnetic radiation and electricity, which impact things without direct touching.
What is a non-contact force?
Electrons doing this in the same direction in materials such as iron, nickel, and cobalt are responsible for magnetism
What is spinning?
This is a short-term event, such as a thunderstorm, wind, or hail
What is weather?
One of the distinct forms in which matter can exist
What is a state of matter?
Gravity, a stretched spring, and chemical structure are all related to this kind of energy
What is potential energy?
When a force changes either the velocity or direction of movement of an object, it is called this.
What is acceleration?
The area influenced by an electric charge or a magnet can be called this
What is an electric or magnetic field?
This causes the sky to appear blue
What is the scattering of light?
