ENERGY AND THE TWO MAIN TYPES
1. Energy is the ability to do work or cause change and occurs in many forms.
2. The two main types of energy are potential energy and kinetic energy.
3. Define Potential Energy: Potential energy is stored energy or energy at
rest. Potential energy can be increased or decreased due to position or
condition.
4. Which skier (A, B, or C) has more potential energy in the picture below? Skier C
has the most potential energy because he/she has the ability to fall
further.
5. Define Kinetic Energy: Kinetic energy is energy of motion or movement.
Anything in motion has kinetic energy. Kinetic energy can be increased
or decreased due to potential energy increasing or decreasing.
6. The amount of kinetic energy a moving object has depends on its mass and its
speed.
7. In each of the following pairs, CIRCLE which would have more kinetic energy
rolling down a hill:
a. A marble or a boulder
b. A beach ball or a bowling ball
c. A toy car or a Hummer
d. WHY did you choose the ones you circled? These objects have more
mass so they will have more kinetic energy rolling down a hill.
8. In the picture below, when does the swinger have the most potential energy?
The swinger has the most potential energy at the A position. When does
the swinger have the most kinetic energy? The swinger has the most
potential energy at the B position. When does the swinger switch from
potential to kinetic energy? The swinger switches from potential to kinetic
energy as she reaches the top of her swing (potential to kinetic) and
the bottom of her swing (kinetic to potential).
9. If an object has more potential energy, how does this affect that object’s kinetic
energy? If an object’s potential energy increases, the object’s kinetic
energy will also increase.
FORMS OF ENERGY (SCREAM H)
10. What is the definition of Sound energy? Sound energy is the movement of
sound waves caused by vibrations.
Example(s) of sound energy: Playing the guitar, violin, singing, etc.
11. What is the definition of Chemical energy? Chemical energy is stored in atoms
and molecules and released in chemical reactions that usually produce heat.
Example(s) chemical energy: batteries, biomass, coal, petroleum.
12. What is the definition of Radiant energy? Radiant energy is light energy that
travels through electromagnetic waves.
Example of radiant energy: the sun, a flashlight, light bulbs, etc.
13. What is the definition of Electrical energy? Electrical energy is the movement
of electrons through conductors that transfers from potential (stored) energy to
kinetic (motion) energy typically when plugged into an electrical outlet. Electrical
energy gives us electricity.
Example of electrical energy: a hair dryer, a toaster, a vacuum, etc.
14. What is the definition of Atomic energy? Atomic energy is energy stored in the
nucleus of an atom. The two ways to release atomic energy are through fusion
(combining atoms to make a new atom) and fission (splitting an atom into two
separate atoms).
Example of atomic energy: nuclear power plants, turbines, etc.
15. What is the definition of Mechanical energy? Mechanical energy is the sum of
kinetic and potential energy in an object that is used to do work. In other words,
it is energy in an object due to its motion or position, or both.
Example of mechanical energy: pushing open a door (human has the potential
energy to do work and the kinetic energy is the actual pushing of the door).
16. What is the definition of Heat energy? Heat energy is energy that deals with
temperature. Forms of heat energy include conduction, convection, and
radiation.
Example of heat energy: (conduction) a pot sitting on a hot burner
(convection) macaroni rising and falling in a pot of
boiling water
(radiation) lying out in the sun to get a tan
Write the form(s) of energy shown in the pictures below.
17. Mechanical Energy
18. Electrical Energy
19. Sound Energy (also
looking at the
mechanical energy if you are
drummer)
20. Atomic Energy
21. Heat Energy
22. Chemical Energy
23. Radiant Energy
(conduction)
Energy Transformations
24. The Law of Conservation of Energy states: Energy cannot be created or
destroyed, it can only be transformed.
25. The streak of lightning is a form of electrical energy that transforms into light
energy and/or sound energy.
26. When you turn a flashlight on, you are transforming chemical and/or
mechanical energy into radiant energy.
27. Turning on the television is a form of electrical/mechanical/chemical (if
using the remote) energy that transforms into light energy and/or sound
energy.
28. A roller coaster sitting at the top of a hill has potential energy that is
transformed into kinetic energy as it comes rushing down the hill.
29. A blow dryer is a form of electrical energy that transforms into heat energy
and/or sound energy.
30. Fireworks are a form of chemical energy that transform into sound energy,
radiant energy, and/or heat energy.
Identify the following examples as conduction, convection, or radiation.
31. Ice in a soft drink melts due to radiation
32. A person placing their hands over a fire radiation
33. Picking up a hot cup of coffee conduction
34. Boiling an egg in water convection
35. A pot touching a hot stove conduction
36. Putting your wet shoes on a floor vent to dry them faster convection
37. Using a heating blanket to get warm conduction
38. A small heater heating a bathroom radiation
39. A cold blooded reptile warming itself from the sun radiation
SCIENTIFIC METHOD
40. If you have ever been shot with a rubber band then you know it has energy in
it, enough energy to smack you in the arm and cause a sting! But just how much
energy does a rubber band have? In this experiment you will be investigating
how the stretching of a rubber band affects the amount of energy that springs
out of it.
