PS.5 Test Review

Front

What is energy conversion?

Back

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

Front

What happens to energy during conversion?

Back

During any energy conversion, some energy is lost to the environment as heat.

Front

What is convection?

Back

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

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.

Front

How can you increase gravitational potential energy?

Back

You can increase gravitational potential energy by raising the height of an object in a gravitational field.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

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 from the sun.

Front

What type of energy is involved in air circulation?

Back

The type of energy involved in air circulation is convection.

Front

What is an example of mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object; for example, a moving car has mechanical energy.
