There is another aspect Of this matter We must look

bodies In motion have energy. II body In motion Is
II strikes Therefore, motion is the form
of energy and when this energy Is given it does work
Then the power OF doing work may be possessed by
bodies ia another way.
WHAT THE STORAGE OF ENERGY MEANS.
We have not only the energy OF motion. but have
the energy Of position. We may confer upon q body by
changing its position the power to do work, and then
are said give that energy For instance raise XII
ogramme weight from the table to the height of metre,
ard haye done upon IL n kiogramme.metre OF work.
andin changing It's position have conferred upon 1t
when 1t was upon the table We give to that change OF
position the name of storage OF energy" In general
we may define the storage of energy to be comforting
upon body the power do WORK In virtue OF a change
In its position The action OF the Taterwhee is caused

METHOD OF PRODUCING ELECTRICITY
The lecturer here illustrated this point by means
o. small electrical machine known ~ Yoss's ma
chine. The string from weight on the table passed
up over q pulley and. descending was wound
around a cy lindcr connected with glass disk. On
turning the wheel the weight assembled and being
allowed to fall. the wheel WIS thereby made to
volvc rapidly and electrical SPARKS were pIoduted.
The lecturer ZEN continued:
