Energy: Conservation and Transfer

What is electricity?

• The flow of electric charge (Current), carried by electrons, through a conductor.

• A type of energy that can be seen and touched.

• A natural phenomenon that occurs in the atmosphere during storms.

• A form of energy that is only produced by batteries.

What is the law of conservation of energy?

• Energy can be created and destroyed.

• Energy can only be transformed from one form to another.

• Energy is a constant that does not change.

• Energy can be created from nothing.

What is an energy source?

• The raw materials used to create useful energy, like heat, electricity, or movement.

• A type of renewable resource that cannot be replenished.

• A method of storing energy for future use.

• A process that converts energy from one form to another.

What is a conductor?

• A material that allows heat or electricity to pass through it easily, such as metals like copper or sea water.

• A substance that prevents the flow of heat or electricity, like rubber or glass.

• A type of electrical device that stores energy, such as a battery.

• A material that can only conduct electricity at high temperatures, like silicon.

What is a Renewable Energy Source?

• Replaced naturally and at a rate faster than they are used.

• A source that is depleted faster than it can be replenished.

• A type of energy that is only available during certain seasons.

• Energy derived from fossil fuels.

What is the most magnetic material?

• Copper

• Iron

• Aluminum

• Gold

What is energy conservation?

• The practice of using less energy by being more efficient or reducing waste.

• The process of generating more energy from renewable sources.

• The act of storing energy for future use.

• The method of increasing energy consumption for economic growth.

What is an example of energy transfer?

• When you heat a pot of water on the stove; heat energy moves from the burner to the pot.

• When you push a swing and it moves back and forth.

• When you turn on a light bulb and it illuminates the room.

• When you pour cold milk into a hot cup of coffee and it cools down.

What is kinetic energy?

• The energy of motion.

• The energy stored in an object at rest.

• The energy released during a chemical reaction.

• The energy associated with an object's position.

What type of energy is produced when a guitar string vibrates?

• Light energy

• Sound energy

• Thermal energy

• Nuclear energy
