We will use the force scale to measure forces. It is calibrated in Newtons.
Here are some things to do to become familiar with forces and how to measure them:
The scale should read zero when there is nothing hanging on it.
Figure out how to adjust the scale's zero reading if it does not.
What is the maximum force this scale can measure (in Newtons)?
Weigh several different objects and give an example of an object that is
nearly the maximum weight the scale can read.
If an object is too light weight for the scale to sense it, how can you
use the scale to determine its weight? For example, determine the weight of
one paper clip (or some other very light object).
The force scale works in other directions, not just when something pulls down on it. It measures the force that pulls on it in any direction.
Hold the scale horizontally and pull on its hook.
Describe how the force you apply to the scale changes as you
pull the hook farther and farther.
Also note that the scale no longer starts at zero. Why not?
