Hey my name is Raven. Today we will be talking about simple machines. The simple machine will be a lever and a wheel and axle.
What are simple machines ? What is a lever and a wheel and axle?
A simple machine makes work easier by multiplying the original amount of force exerted changing direction of the force. First, of all the lever is a long bar with a fulcrum. The force ad the load go in opposite directions.
oh....like a triple beam balance!!!!!!
Oh...like a bicycle and cars!!!!!
A wheel and axle are two wheels connected by a center post(axle). The force and the load move in the same direction.
Yeah you got it!!!
