8th Grade Energy flashcard

Front

Energy due to motion is ____________ energy.

Back

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

Front

What is charging by induction?

Back

Charging by induction is the process of charging an object without direct contact, where a charged object causes the redistribution of charges in a neutral object.

Front

How does heat transfer occur through radiation?

Back

Heat transfer through radiation occurs through the emission of electromagnetic waves.

Front

What happens to molecules during conduction?

Back

During conduction, molecules move faster and collide more frequently, transferring heat energy.

Front

What type of heat transfer circulates air in a room when a heater is turned on?

Back

Convection is the type of heat transfer responsible for the circulation of air in a room.

Front

Define potential energy.

Back

Potential energy is the stored energy in an object due to its position or state.

Front

What is the difference between conduction and convection?

Back

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

Front

What is an example of charging by contact?

Back

Charging by contact occurs when a charged object touches a neutral object, transferring charge directly.

Front

What is thermal energy?

Back

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

Front

Explain the principle of conservation of energy.

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
