Flashcard 2.2

Front

What type of energy is associated with electrons flowing through a wire?

Back

Electrical energy is the energy associated with the flow of electric charge, typically through a conductor like a wire.

Front

This is an example of _____________ energy.

Back

Elastic energy is the potential energy stored in an object when it is compressed or stretched.

Front

Explain the energy transformation that begins with a battery.

Back

The energy transformation is chemical energy (from the battery) to electrical energy (as it flows through a circuit) to light energy (when it powers a light bulb).

Front

Energy of motion is ____________.

Back

Kinetic energy is the energy that an object possesses due to its motion.

Front

What is the process called when a snowman melts in the sun?

Back

Radiation is the transfer of energy through electromagnetic waves, which is how the sun's heat melts the snowman.

Front

Define 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 kinetic energy?

Back

Kinetic energy is the energy an object has due to its motion, calculated as 1/2 mv², where m is mass and v is velocity.

Front

What type of energy is stored in food?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like those found in food.

Front

What is the difference between conduction and convection?

Back

Conduction is the transfer of heat through direct contact, while convection is the transfer of heat through the movement of fluids.

Front

What is an example of gravitational energy?

Back

Gravitational energy is the potential energy held by an object because of its height, such as water stored in a dam.
