Who does the work when riding a horse or rider?

This is a tricky question because it depends on how you define "work."

The horse does the physical work:

* The horse provides the power to move, carrying the rider and overcoming the forces of gravity and friction.

* The horse uses its muscles to propel itself forward, jump over obstacles, and maintain balance.

The rider does the mental and directional work:

* The rider provides the instructions and guidance for the horse to follow.

* The rider uses their body language, voice commands, and reins to steer, control speed, and navigate the horse.

It's a partnership:

* While the horse does the physical labor, the rider is responsible for guiding and directing the horse.

* A successful partnership requires both the horse and rider to understand and communicate with each other.

So, in essence, both the horse and rider contribute to the task of riding. The horse provides the power, while the rider provides the direction.
