Period 2 Activity Sheet Solutions: Forms of Energy
2.1 How are Forms of Energy Defined?
Your instructor will discuss the forms of energy that we will study in the World of Energy.
Give an example of each form of energy listed below.
a)
Mechanical Energy of Motion
Energy exhibited by objects in motion. Example: any moving
object.
b)
Thermal Energy
Unorganized energy of motion exhibited by vibrations of atoms and
molecules. Example: Example: rub hands together.
c)
Sound Energy
Organized energy of motion exhibited by vibrations of atoms and
molecules. Example: any sound.
d)
Electrical Energy
Energy resulting from the forces between charged particles.
Example: Electrical energy from a hand-cranked generator lights a
bulb.
e)
Magnetic Energy
Energy resulting from the forces between magnets, causing the
magnets to attract or repel. Example: one magnet floats above
another magnet.
f)
Radiant Energy
Energy resulting from the vibrations of charges, such as radio
waves, microwaves, light rays, and X-rays. Example: radiant energy
from a floodlight shining on a solar cell powers the free play radio.
g)
Gravitational Potential Energy
Energy stored in raised objects, which have the potential to fall.
Examples: water wheel or any raised object.
h)
Strain Potential Energy
Energy stored in stretched or compressed objects, such as springs.
Examples: music box and wind-up toys.
i)
Electrical Potential Energy
Energy stored in the separation of static (not moving) electric
charges. Example: capacitor
j)
Chemical Potential Energy
Energy available in the chemical bonds between atoms or molecules.
Example: battery
k)
Nuclear Energy
Energy available in the nucleus of atoms that can decay. Examples:
smoke detector, the Sun
