A toaster is a common kitchen appliance. It works by plugging the toaster into an electric outlet. A person can put their bread into a slot on top of the toaster. A toaster has coils inside it that will heat up. Once a person puts their bread into the slots in the toaster, the heated coils will brown their bread. The bread will pop up out of the toaster when it is ready. What type of energy is being transferred?

• Light energy to electrical energy

• Sound energy to heat energy

• Sound energy to electrical energy

• Electrical energy to heat energy

What energy transformation takes place in a light bulb?

• Light energy changes into heat energy.

• Light energy changes into electrical energy.

• Electrical energy changes into light energy.

• Chemical energy changes into heat energy.

Energy is the ability to make something​ (a)  

• move,happen, or change
• stop moving due to friction
• move, happen, or stop

Energy moving from one place to another

• friction

• tranfer

• trap

• transformation

What is the main energy transfer for an apple falling from a tree?

• Kinetic energy → elastic potential energy

• Chemical energy → gravitational potential energy

• Gravitational (potential energy) → kinetic energy

• Thermal energy 

_{Which form of energy is mostly produced in this transformation?}

• Electrical
• Mechanical
• Thermal
• Sound

Identify the energy transfer

• mechanical (movement) to sound

• chemical to electrical

• sound to mechanical

• thermal to sound
