Energy Transfer

What is energy?

• It makes things happen! (Or more formally: the ability to do work)
• It makes things happen! (Or more formally: the ability to move cells)
• It does not makes things happen!

What is energy transfer?

• Energy being moved from across boundaries.
• Energy being moved from cell to cell.
• Energy being moved from place to place.

What is a generator?

• Changes energy from two forms to another.
• Changes energy from one form to another.
• Changes energy from chemical to solid.

What is a battery?

• Acid can change it from one form to another.
• Store energy and change it from two form to another.
• Store energy and change it from one form to another.

What is a solar cell?

• Converts energy of kinetic energy into electrical energy.
• Converts energy of heat into electrical energy.
• Converts energy of sunlight into electrical energy.

What is motion energy?

• The energy something has due to movement.
• The energy something has due to kinetic energy.
• The energy something has due to light energy.

What is a wind turbine?

• A device that produces energy by spinning small blades, which in turns spins a generator to make electricity.
• A device that produces energy by spinning big blades, which in turns spins a generator to make electricity.
• A device that makes energy through electricity.

What is kinetic energy?

• is a property of a moving object or particle and depends not only on its motion but also on its mass.
• is a chemical property of a object or particle and depends not only on its motion but also on its mass.
• is energy that stays still

Example of heat transfer
