In this simple machine, a wheel is locked to a central axle and they rotate each other when a force is applied on either one of them.

0:30

When we place a heavy load on the axle and push it, the rolling of the wheels reduces the friction to a large extent

0:39

However, the frictional force does not depend on the surface area of the object.

0:48

The friction depends on its mass and what material it is made of.

0:52

When there is less friction, it takes less force to move something.

0:57

The effort needed to overcome the resistance, acting upon the axle is relatively small.

We see the wheel and axle setup in many of our day to day activities.

https://mocomi.com/ presents: Wheel and Axle - Simple Machines When we have to move a real heavy load, we have to use a great deal of force to push it, because of: Frication: Force resisting the motion of the object on the ground. Gravitational force: Force that pulls the object to the ground. The “Wheel and axle” solves this problem in jiffy! Learn about this simple machine, and see how it reduces the effort required to move certain objects through this fun and animated learning module. Watch this animated video to learn more about this simple machine and How does a wheel and axle benefit us when it comes to moving a heavy load? #WheelAndAxle #SimpleMachines #Science To learn more about wheel and axle go to: https://mocomi.com/wheel-and-axle/ For more fun learning physics videos and articles go to: https://mocomi.com/learn/science/phys...
