A simple machine that rotates about a pivot
Explanation
A lever is defined as a simple machine that rotates around a fixed point called the pivot, allowing for the amplification of force.
Common mistake
Misunderstanding Lever Functionality
Students often think that a lever creates energy rather than simply transferring force and changing the direction of the applied force.
Emphasize that a lever does not create energy; it only allows a smaller force to move a larger load by increasing the distance from the pivot.
