Energy CIA 3 Review

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases). Warm air rises while cool air sinks, creating a cycle.

Front

What is the energy transformation when a flashlight shines?

Back

The energy transformation is chemical energy → electrical energy → light energy.

Front

What is the purpose of an electric motor?

Back

The purpose of an electric motor is to convert electrical energy into mechanical energy.

Front

What type of energy is associated with motion?

Back

Kinetic energy is the energy of motion.

Front

What shows an energy transformation from chemical energy to electrical to light energy?

Back

A battery causes a flashlight to shine.

Front

What is conduction?

Back

Conduction is the transfer of heat through direct contact between materials.

Front

What is radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat from the sun.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state, such as a ball at the top of a hill.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is energy of motion, while potential energy is stored energy based on position.

Front

What is an example of energy transformation in a battery?

Back

A battery transforms chemical energy into electrical energy.
