Answer 1

$\huge\star\underline\mathfrak\purple{Answer}$

A lever enables people to do work using less force. A lever usually is used to move or lift objects. Sometimes it is used to push against objects, but not actually move them. Levers can be used to exert a large force over a small distance at one end by exerting only a small force over a greater distance at the other.
