What is a wheel and axle? Wheel and axle: a simple machine that is used to change circular motion into forward motion A wheel reduces the friction between an object and a surface, making it much easier to move
They work by spinning the axle attached to a wheel, transferring the force forward over a larger distance wheel axle
The axle is firmly attached to the wheel As force is applied to spin the axle, it is transferred to the wheel The wheel reduces the friction that would be put on an object by dragging it along the ground force
What are some examples of wheel and axles you might see in your daily lives?
What are some examples of wheel and axles you might see in your daily lives?
Wheel and axels are used when objects have to be moved over long distances Using a wheel and axle greatly reduces the friction put on an object as it moves along the ground
Instead of a whole object being slowed by friction, only the wheels underneath have any contact with the ground This allows the object to be moved with ease!
Types of Wheel and Axles Fixed Axle: when the axle is firmly attached to the wheel The rotation of the axle is transferred into forward motion of the wheel When an wheel is not fixed in place, it is able to turn independent of the axle This is found in pulleys!
Types of Wheel and Axles fixed not fixed
Lets try it! Use different types of wheel and axles to move different weights! Write down your observations
