PS.5 Test Review

Front

What is energy transfer?

Back

Energy transfer is the process of moving energy from one location to another or transforming it from one form to another.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field, typically related to its height above the ground.

Front

What type of energy is associated with motion?

Back

Kinetic energy is the energy associated with the motion of an object.

Front

What is convection?

Back

Convection is the transfer of heat through the movement of fluids (liquids or gases) caused by differences in temperature and density.

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 radiation?

Back

Radiation is the transfer of energy through electromagnetic waves, such as light or heat, without the need for a medium.

Front

What is an example of energy conversion in a hair dryer?

Back

When you turn on a hair dryer, electrical energy is converted into kinetic energy (the movement of air), thermal energy (heat), and sound energy.

Front

What is the source of thermal energy in cooking?

Back

The source of thermal energy in cooking is typically fire or an electric heating element.

Front

What happens to gravitational potential energy when an object is raised higher?

Back

When an object is raised higher, its gravitational potential energy increases due to its increased height in the gravitational field.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.
