Energy and Earth Part 2

Front

What type of energy do wind turbines convert into electrical energy?

Back

Kinetic energy is the energy of motion, which wind turbines harness from moving air.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases), where warmer, less dense areas rise and cooler, denser areas sink.

Front

What is the relationship between temperature and kinetic energy?

Back

High temperature is associated with high kinetic energy, meaning that particles move faster at higher temperatures.

Front

What is electrical energy?

Back

Electrical energy is the energy of moving electrons, which can be harnessed to power devices.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, such as a stretched rubber band.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

What is mechanical energy?

Back

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

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials, where heat moves from the hotter object to the cooler one.

Front

What is thermal energy?

Back

Thermal energy is the total kinetic energy of particles in a substance, related to its temperature.

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as converting kinetic energy to electrical energy.
