3. Balance
Those Masses!

4. Only a small effort is required to lift/move a heavier load.
However, the smaller the effort,
the further the distance required
from the fulcrum.

5. LET’S LEARN ABOUT LEVERS

6. The EFFORT is the force that is used to move the lever.
The LOAD is the object to be moved.
The FULCRUM is the point at which the lever pivots.
