Unit 3 Study Guide

Front

What is wind power?

Back

Wind power is the process of converting wind energy into electricity using wind turbines.

Front

What is a disadvantage of using wind power?

Back

It is not always windy, which can lead to inconsistent energy production.

Front

What are fossil fuels?

Back

Fossil fuels are natural substances formed from the remains of ancient plants and animals, used as energy sources, and are considered nonrenewable.

Front

What is biomass energy?

Back

Biomass energy is derived from organic materials like plants and waste, which can be converted into energy through burning.

Front

What is the difference between renewable and nonrenewable energy?

Back

Renewable energy can be replenished naturally (e.g., solar, wind), while nonrenewable energy comes from sources that cannot be replaced (e.g., fossil fuels).

Front

What are solar farms?

Back

Solar farms are large-scale installations that use solar panels to capture sunlight and convert it into electricity.

Front

What is the initial investment in solar energy compared to coal energy?

Back

Solar farms require a high initial investment but offer long-term cost savings, while coal plants have lower initial costs but may not provide the same long-term savings.

Front

What type of energy is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often associated with heat.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a rock at the top of a hill.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object, used to perform work.
