Kinetic and Potential Energy

I can identify types of energy, including potential and kinetic.

Definition of Energy…

The ability to do work or cause change.

Energy has 2 main classifications:

potential energyor

kinetic energy.

Potential EnergyPotential Energy

• Potential energyPotential energy– Stored up energyStored up energy

or energy at rest.or energy at rest.

KINETIC ENERGY:KINETIC ENERGY:

Energy in Energy in motionmotion

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.

____________ energy?

________ energy?

potential

kinetic

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

Where do we get our energy from?

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 greatest amount of potential energy?

It is the highest point, so it will fall the furthest, so it has more potential energy.

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.

When the bow string is pulled back all the way, the type of energy demonstrated would be _______________ energy. potential
