4 th Grade Science Ch. 5-6 Forces and Motion Mrs. Thornburgs version.
Simple Machines All machines are made from the six simple machines: lever, inclined plane, wedge, screw, wheel and axle, and pulley.
Lesson 3: How are work and Motion related?. Work – the result of a force MOVING an object.
Simple Machines. the use of force to move an object over a distance.
Simple Machines Chapter 5 Section 3. Lever A lever is a bar that is free to pivot or turn around a fixed point. The lever pivots on a fulcrum. The input.
Motion and Force Speed, Velocity, Slope, Friction, and Distance.
They are made with FEW or no moving parts. WHEEL & AXLE SCREW WEDGE INCLINED PLANE PULLEY LEVERGEAR.
Vocabulary for Simple Machines Study these terms for your vocabulary test.
Simple Machines!. Simple Machines Make work use less force by increasing the distance –When effort distance increases, effort force decreases! Six different.

Simple machines in the real world.. Machine- something that makes work seem easier by changing the size or direction of a force.
Topic: Simple Machines PSSA: C / S8.C.3.1. Objective: TLW compare different types of simple machines. TLW compare different types of simple machines.
Simple Machines There are 6 types of simple machines: the inclined plane, the wedge, the screw, the lever, the pulley, and the wheel and axle.
Simple Machines By: Kelsey. Levers A lever is a simple machine that consists of a bar that pivots at a fixed point, called a fulcrum. Levers are used.
SIMPLE MACHINES. WORK Using force to move an object.
One kind of lever is the first-class lever. A first-class lever has a fulcrum in the middle. A fulcrum is a object that supports the bar and allows it.
