Vocabulary
This is the ability to cause change
What is energy?
This is the energy conversion that happens when you turn on a light
What is electrical energy turns into light, thermal, and sound energies?
This type of energy is obtained from the sun
What is solar energy?
This is an energy resource that CAN be replaced as fast as it is used (within our lifetime)
What is a renewable energy resource?
These two things affect kinetic energy
What are speed and mass?
This states that energy can be transformed from one form to another or transferred from one region to another, but cannot be created or destroyed
What is the law of conservation of energy?
This is the energy conversion that takes place as a skateboarder rides down a ramp
What is potential energy at the top of the hill to a combination of potential AND kinetic energy while riding down the hill?
This type of energy is obtained through falling water
What is hydroelectric?
This is an energy resource that CANNOT be replaced faster than it is used
What is nonrenewable energy resource?
These are two general forms of energy
What are kinetic energy and potential energy?
This is the force that resists the sliding of two surfaces that are touching
What is friction?
This is the energy conversion that happens when you turn on a microwave oven
What is electrical energy turns into light (radiant), thermal (heat), and sound energies?
This type of energy is obtained through atoms splitting or uniting
What is nuclear energy?
This type of energy resource can NEVER be used up
What is inexhaustible energy?
This is the most common form of waste energy
What is thermal energy?
These are the remains of ancient organisms that can be burned as an energy source
What are fossil fuels?
This is the energy conversion that happens in a hydroelectric power plant
What is water stored behind a dam (potential energy), then water rushes down a tunnel (kinetic energy) which turns a turbine (mechanical energy) which turns a generator (electrical energy)?
This type of energy is obtained through the burning of dead plants and animals
What is biomass?
These are three types of fossil fuels
What are coal, petroleum, and natural gas?
This is how to reduce the effects of friction
What is add a lubricant, like oil?
This is the total energy of an object or group of objects due to large-scale motions and interactions
What is mechanical energy?
This is the energy conversion that happens in an electric power plant
What is coal (chemical energy) gets burned (thermal energy) which allows steam to turn a turbine (mechanical energy) which turns a generator (electrical energy)?
These are the eight types of energy mentioned in the first section of Chapter 5
What are mechanical, potential, kinetic, radiant, electric, nuclear, thermal, sound?
These are the three types of potential energy
What are gravitational, elastic, and chemical?
This is the energy conversion that takes place in a geothermal power plant
What is heat from the earth (thermal energy) heats up water to make steam (thermal energy) which turns a turbine (mechanical energy) which turns a generator (electrical energy)?
