Jason Day 1.  A lever is an object consisting of a rigid bar or plank that pivots at a certain point. Often used to lift an object at a second point.
Lever A lever is a bar that is free to turn, about a fixed point.
Chapter machines Machines A device used to multiply forces or simply to change the direction of forces.
 A machine is an instrument that multiplies force to make work faster and easier. We can classify machines into two groups, depending on faster complexity:

LEVERS By: Emma S, Jake A, Thomas A All about levers  A lever is a simple machine that allows you to gain a mechanical advantage in moving an object.
Work, scientifically speaking, is done on an object when a force is applied to move it a certain distance. IMPORTANT! The distance (displacement) in this.
Levers Simple Machines. Levers are used to help lift heavy objects.
Simple Machines!. Simple Machines Make work use less force by increasing the distance –When effort distance increases, effort force decreases! Six different.
Levers A lever is a rigid bar that pivots (rotates) about a fixed point. Levers are used to change the magnitude, direction, or speed of forces that act.
Machines. Simple Machines  Work out is less than or equal to Work in.  Force out can be greater than Force in.

Levers Lever is a simple machine that allows you to gain a mechanical advantage in moving an object or in applying a force to an object.
Work and Simple Machines
A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge or fulcrum. A lever amplifies an input force to provide a greater.
