| Mass
is the amount of matter an object has. We often use a triple-balance
beam to measure mass.
A triple-beam balance gets its name because
it has three beams that allow you to move known masses along the
beam.
Here is a
picture of a triple beam balance. You probably have used one in
school.
There
are also many other types of balances. Scientists need balances
that can measure very small amounts of mass.
If you are
interested at looking at the many other types of balances click here.
If you are
using a triple beam balance in school you might want to brush
up on your skills on how to use a triple-beam
balance
Because a
triple beam balance compares a known mass to an unknown mass it
is unaffected by gravity. Unlike a spring scale which really measures
weight, the triple beam balance gives a true measure of mass.
Do you often
get confused between mass and weight? Check out the Mass vs. Weight Page
Now it's
time to practice your skills using the triple-beam balance.
Problem
1:
A block is
put onto a triple beam balance.
What
is the mass of the object (to the closest tenth of a gram?
Click on the
picture below and get a closer look at reading the scale after
the scale has been balanced. Remember to find the mass using a
triple beam balance you must add the mass values of each of the
three beams.
