Potential EnergyPotential Energy
• Potential energyPotential energy– Stored up energyStored up energy
or energy at rest.or energy at rest.
Potential energy is stored energy or energy at rest.
What point would have the greatest amount of potential energy?
It is the highest point, so it will fall the furthest, so it has more potential energy.
Kinetic energy is energy in motion.
The greatest kinetic.
Where would the greatest kinetic energy be?
Kinetic energy is …..
energy in motion.
As potential energy decreases, kinetic energy increases. So, the greatest amount of kinetic energy would be….
just before the ball hits the ground.
When the bow string is pulled back all the way, the type of energy demonstrated would be _______________ energy. potential
Once the string is let go the arrow will fly toward the bulls eye. The arrow moving demonstrates ___________ energy.kinetic
We can now look at other forms of energy and classify them as
either potential energy or kinetic energy
ElectromagneticEnergy?
o Light energy
o Includes energy from gamma rays, xrays, ultraviolet rays, visible light,
infrared rays, microwave and
radio bands
Nuclear energy –
Nuclear power plants, atomic Nuclear power plants, atomic bomb, stars (sun- solar energy)bomb, stars (sun- solar energy)
Chemical Energy
o Energy released from chemical
reactions.
Chemical energy is stored on the end
of a match.
Where do we get our energy?
When we eat food, what type of reaction occurs to give us the energy?
CHEMICAL
Plants take in the energyfrom the sun.
They use this energyin a CHEMICALprocess ofphotosynthesis to makefood for the plant togrow.

Potential energy is stored energy or energy at rest.
What point would have the least amount of potential energy?
The lowest point would have the least amount of stored energy or potential energy.
Kinetic energy is …..
energy in motion.
As potential energy decreases, kinetic energy increases. So, the greatest about of kinetic energy would be….
just before the ball hits the ground.
