Energy
is a key principle in
physics
, allowing
work
to be
done.
The
rate
at which
energy
is
transferred
is called
power
and the
amount
of
energy
that is
usefully transferred
is called
efficiency.
Electrical appliances
use
energy
and
work.
When a
force
causes a
body
to
move
,
work
is being done on the
object
by the
force.
Work
is the measure of
energy transfer
when a
force
(
F
) moves an object through a
distance
(
d
).
One
joule
of
work
is
done
(or one
joule
of
energy
is
transferred
) when a
force
of one
newton
causes a
body
to
move
through a
distance
of one
metre.
A horizontal force of 50 N causes a trolley to move a horizontal distance of 30 m, so the work done on the trolley by the force is
1
,
500
J.
12,000
J of energy is supplied to move a small truck a distance of
80
m, indicating the size of the force applied is
150
N.
