1. Kinetic and Potential Energy
Today we are going to learn about Kinetic and Potential energy.
I can identify types of energy, including potential
and kinetic.

2. The ability to do work or cause change.
Definition of Energy…
The ability to do work or cause change.
In order to understand the different forms of energy, you have to know what the term “energy” means. Energy is the ability or the capacity of an object to do work. This is measured in two different ways : capability of doing work- known as potential energy, and the conversion of the capability to motion- called kinetic energy.

3. Energy is classified as either potential energy or kinetic energy.

4. Potential Energy
Potential energy
Stored up energy or energy at rest.

5. KINETIC ENERGY:
Energy in motion

6. Potential energy is
stored energy or energy at rest.
It is the highest
point, so it will
fall the furthest,
so it has more
potential energy.
What point would have the greatest amount of
potential energy?

7. Potential energy is
stored energy or energy at rest.
The lowest point would have the least amount
of stored energy or potential energy.
What point would have the least amount of
potential energy?

8. 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.

9. potential
____________ energy?
kinetic
________ energy?

10. When the bow string is pulled back all the way, the type of energy demonstrated would be
potential
Once the string is let go the arrow will fly toward the bulls eye. The arrow moving demonstrates ___________ energy.
kinetic

11. We can now look at other forms of energy and classify them as either potential energy or kinetic energy

food

26. Where do we get our energy from?

28. Where do we get our energy?
When we eat food, what type of reaction occurs
to give us the energy?
CHEMICAL

29. Plants take in the energy
from the sun.
They use this energy
in a CHEMICAL
process of
photosynthesis to make
food for the plant to
grow.

31. Potential energy is
stored energy or energy at rest.
It is the highest
point, so it will
fall the furthest,
so it has more
potential energy.
What point would have the greatest amount of
potential energy?

32. Potential energy is
stored energy or energy at rest.
The lowest point would have the least amount
of stored energy or potential energy.
What point would have the least amount of
potential energy?

33. 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.

34. potential
____________ energy?
kinetic
________ energy?

35. When the bow string is pulled back all the way, the type of energy demonstrated would be
potential
Once the string is let go the arrow will fly toward the bulls eye. The arrow moving demonstrates ___________ energy.

41. Potential energy is
stored energy or energy at rest.
It is the highest
point, so it will
fall the furthest,
so it has more
potential energy.
What point would have the greatest amount of
potential energy?

42. Potential energy is
stored energy or energy at rest.
The lowest point would have the least amount
of stored energy or potential energy.
What point would have the least amount of
potential energy?

43. 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.
