Energy Transfer

•Thermal Energy is energy that is created in the movement of particles (atoms) that produces heat.

What does thermal energy produce?

• Electricity

• Heat

• Air

Heat (thermal) energy increases as temperature increases.

Does heat energy increase as temperature increases?

• no

• yes

Mechanical energy is energy of motion. It is the total energy of motion and position of an object. Mechanical energy can be all potential, all kinetic energy, or some of each.

Mechanical can be what?

• potential energy only

• kinetic energy only

• all potential, all kinetic energy, or some of each

•The mechanical energy of an

object stays the same, but the

potential and kinetic energy of

an object can increase or decrease.

Does mechanical energy stay the same?

• yes

• no

Potential energy refers to position of an object. Potential energy is the energy possessed by a body by virtue of its position relative to others. Which is an example of potential energy?

• a child at the top of a slide

• a roller coaster going down the hill

• a car going up a hill

Kinetic energy refers to motion. It is energy which a body possesses by virtue of being in motion.

Which is an example of Kinetic energy?

• A flying airplane

• a car at a stop light

• a rock at the top of a cliff

Which is an example of kinetic energy?

• a pencil falling to the floor

• a yo-yo before it is released

• a rock sitting on the edge of a cliff

Light energy is created by vibrating particles that create waves that travel through space and time. [These waves are called electromagnetic waves.]

How is light energy created?

• by kinetic energy

• by vibrating particles that create waves that travel through space and time

• by vibrating particles that do not create waves

Light energy

•Includes energy from gamma rays, x-rays, ultraviolet rays, visible light, infrared rays, microwave and radio bands.

What is an example of light energy?

• a desk

• a microwave

• a table
