What is the Law of Conservation of Energy?

This video explains the law of conservation of energy, which states that energy cannot be created or destroyed but only converted from one form to another. It introduces various types of energy, including radiant, thermal, electrical, sound, nuclear, and electromagnetic energy. The video also provides examples of energy conversions, such as fireworks converting chemical energy to light and sound, wind turbines converting kinetic energy to electrical energy, and light bulbs converting electrical energy to radiant and thermal energy.

What does the law of conservation of energy state?

• Energy can be created and destroyed.

• Energy is only destroyed but not created.

• Energy is only created but not destroyed.

• Energy is neither created nor destroyed, only converted.

Which type of energy is associated with the flow of electrons?

• Nuclear energy

• Sound energy

• Electrical energy

• Thermal energy

What is an example of radiant energy?

• Light from the sun

• Electricity from a power plant

• Sound from a speaker

• Heat from a fire

How do wind turbines convert energy?

• They convert thermal energy to sound energy.

• They convert kinetic energy to electrical energy.

• They convert nuclear energy to radiant energy.

• They convert sound energy to thermal energy.

What type of energy conversion occurs in a light bulb?

• Kinetic energy to electrical energy

• Electrical energy to radiant and thermal energy

• Nuclear energy to thermal energy

• Electrical energy to sound energy
