A wheelbarrow works due to the application of forces like leverage and balance. When weight is placed in the barrow, the wheel serves as a fulcrum, allowing for easier transport of heavy loads by reducing the amount of force needed to lift and move them.
The wheelbarrow is not moving because the forces are balanced, resulting in no net force.
Friction between the wheelbarrow wheels and the ground allows the wheelbarrow to move when force is applied. Without friction, the wheels would simply slip and the wheelbarrow wouldn't move forward easily. However, too much friction can make it harder to push the wheelbarrow.
When a wheelbarrow is used, the person pushing it supplies mechanical energy to overcome frictional forces and lift the load. Some of the person's chemical energy from metabolism is converted into kinetic energy to move the wheelbarrow, and potential energy when lifting the load.
A wheelbarrow is a simple machine that works as a class 2 lever. The handle of the wheelbarrow acts as the lever arm, the load (such as dirt or rocks) is the resistance, and the pivot point (fulcrum) is the wheel. By applying a force on the handle, the wheelbarrow allows you to easily lift and move heavy objects.
If the input force applied to the handles of the wheelbarrow is 202 N, and the wheelbarrow is at equilibrium (not accelerating), the output force required to lift the load would also be 202 N to balance the forces and lift the load.
"I used the wheelbarrow to do the yard work." =P

It is unknown which person specifically invented the ancient Chinese wheelbarrow. My guess is that multiple people contributed ideas to make it work.
Scissors Wheelbarrow Thats all i can think of right now
It distributes weight upon a certain point, usually not on the user, to make moving objects easier; such as a wheelbarrow, pulley, inclined plane, etc.

a wheelbarrow
It has no motor so it takes more work
