Energy is the ability to cause changechange in an object.• The change can involve either the motionmotion or the positionposition of an object or its particles.• Energy can exist in many different formsforms. •We will focus on five types of energy this year.
Can you guess what kind of energy each picture represents?

SC Standard 6-5.1
- All matter is made up of particlesparticles too small to be seen. These particles are always moving.
- Thermal energy is the energy of the motionmotion of these particles. Since allall matter has particles that move, allall matter has thermal energy.

Heat Energy (continued)- As heat is added to a substance, the particles move
fasterfaster and the temperature goes up.
- The faster the particles move, the higherhigher the temperature.
- Sources of heat energy: the SunSun, electricityelectricity, or any material that is burningburning (wood, candle wax, coal).

Thermal Energy and Heata. All matter is made up of particles too small to be seen.
These particles are always moving.b. Thermal energy is the energy of the motion of these
particles. All matter has thermal energy because all matter is made of particles that move.
c. Heat energy is the transfer of thermal energy.d. As heat is added to a substance, the particles move
faster and the temperature goes up.e. The faster the particles move, the higher the temperature.f. Sources of heat energy: the Sun, electricity, or any material
that is burning (wood, candle wax, coal).

Done
The particles in ice do not move, since ice is very cold.
The particles in ice do not move, since ice is a solid.
The particles in ice move slowly, since ice is very cold.
The particles in ice move quickly, since ice is very cold.
Particles in the Sun move quickly because the Sun is very hot.
Particles in the Sun move slowly because the Sun is in space.
Thermal Energy and Heat

- Solar Energy is energy from the Sun, which provides heatheat and lightlight energy for Earth.
- Solar cells can be used to convert solar energy into electricalelectrical energy.

Chemical and Electric Energy
SC Standard 6-5.1
- Mechanical energy comes in two forms.o the motion motion of an object (kinetic energy)o the position position of an object (potential
energy)
Mechanical Energy
SC Standard 6-5.1
- Mechanical kinetic energy is the energy an object has due to its motionmotion.
- A movingmoving car has kinetic energy.- If a car moves fasterfaster, it has more kinetic
energy.
Mechanical Kinetic Energy
SC Standard 6-5.1
- Mechanical potential energy is stored energy related to the positionposition of an object.
- A stretchedstretched rubber band has potential energy because it will move when let go.
- Water behind a dam has potentialpotential energy because it can fall down the dam.
