Energy Conversion Flashcard

Front

What type of energy is converted into electrical energy by the generator?

Back

Kinetic energy is converted into electrical energy by the generator.

Front

True or False: The energy-capturing knee brace uses kinetic energy to power external devices directly.

Back

False. The energy-capturing knee brace does not power external devices directly.

Front

What is the purpose of springs in an energy-capturing backpack?

Back

The heavy part of an energy-capturing backpack is suspended from springs to facilitate bouncing.

Front

True or False: Kinetic energy from the bicycle wheel can be converted into electrical energy.

Back

True. Kinetic energy from the bicycle wheel can be converted into electrical energy.

Front

True or False: The electrical energy generated is used directly to power devices without being stored first.

Back

False. The electrical energy generated is typically stored before being used to power devices.

Front

Define kinetic energy.

Back

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

Front

What is potential energy?

Back

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

Front

Explain the principle of energy conversion.

Back

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

Front

What is a generator?

Back

A generator is a device that converts mechanical energy into electrical energy.

Front

Give an example of energy conversion in everyday life.

Back

An example of energy conversion is a wind turbine converting kinetic energy from wind into electrical energy.
