Energy Essentials
This is defined as the ability to do work or cause change.
What is Energy?
This type of energy is created by the constant motion of atoms and molecules.
What is Thermal energy?
This energy type is stored in the nucleus of an atom.
What is Nuclear energy?
In a campfire, chemical energy in wood is transformed into these two other forms of energy.
What are Thermal and Radiant energy?
These harness wind to turn large spinning blades connected to a generator.
What are Wind turbines?
These resources are made from the buried remains of plants and animals over millions of years.
What are Fossil fuels?
These are the two broad classifications for energy that is either moving or stored.
What are Kinetic and Potential energy?
An example of this type of energy is throwing a baseball.
What is Mechanical Energy?
Stretched rubber bands or compressed springs store this specific form of potential energy.
What is Elastic energy?
This oppositional force resists motion between two objects and often gives off thermal energy.
What is Friction?
This is a major benefit of renewable resources compared to non-renewable ones in regards to the atmosphere.
What is they produce little to no greenhouse gas emissions?
Nuclear power plants primarily use this process of splitting atoms to release energy.
What is nuclear fission?
This law states that energy cannot be created or destroyed, only transformed.
What is the Law of Conservation of Energy?
Kinetic energy specifically depends on these two factors of a moving object.
What are mass and speed?
This type of potential energy increases as the object is lifting higher, away from the Earth's surface.
What is Gravitational Energy
This is a specific frictional force where air particles slow an object's motion.
What is Air resistance?
This resource uses the "photovoltaic effect" to convert sunlight into electricity.
What are Solar panels?
This is a disadvantage of using fossil fuels.
What is they:
- will eventually run out
- what is they are worse for the environment
Most forms of energy and their transformations on Earth can be traced back to this primary source.
What is the Sun?
Radiant energy is transferred by these types of waves that travel outward in all directions.
What are Electromagnetic (EM) waves?
Digestion is a biological process used to release this type of energy from food for movement and warmth.
What is Chemical energy?
When energy is transformed from one form to another, this happens to the total amount of energy.
What is it stays the same?
Hydroelectric dams create a reservoir to store this type of potential energy, which then allows water to flow down into a turbine.
What is Gravitational Energy?
This is a benefit of using a non-renewable resource like fossil fuels.
What is they are:
- energy efficient
- can work regardless of circumstance
Energy is measured in this unit, often abbreviated as "J."
What are Joules?
This form of energy travels by vibrating particles it interacts with.
What is Sound energy
This item stores chemical potential energy and is used to power electrical devices.
What is a battery.
This device converts mechanical energy into electrical energy, and is used in different types of power plants.
What is a generator
This renewable energy type is created from organic materials that come from living things like plants.
What are Biofuels?
In a nuclear power plant, the energy from fission is first used to do this so that a turbine has something to interact with.
What is boil water to create steam?
