This is an interesting question. A Newton
meter is a device that measures Newtons. All
Newton meters are related to the unit of force
called a “Newton”.
In the system of units MKS, which
means “meters”, “kilograms”, “seconds”, a Newton
is the amount needed to accelerate 1 kilogram of
mass at the rate of 1 meter per second squared;
One second type of Newton meter is used to
measure energy. A unit of energy is called
a “Joule”. If you apply a force of 1 Newton on
an object for a distance of 1 meter, then you
are using 1 Joule of energy. One way of
measuring the Joules of energy is by using a
Newton meter of this type.
A third type of Newton meter is used to
measure “torque”. A “torque” is a turning force.
If you apply a force of 1 Newton at a distance
of 1 meter from the pivot at right angle to the
radius, then you are applying a torque of 1
The most common design for a Newton meter is
a cylinder containing a spring inside. You can
attach objects to the spring by a hook. When
any object is attached to the spring, it causes
a force that causes the spring to expand. You
can read how much force is acting on the meter
by using a gauge on the cylinder.
