I don't understand the physics work power and energy unit

Work and energy are the same thing. Their unit is the Joule.

One joule means the energy it takes to push with a force of 1 newton

through a distance of 1 meter.

The unit of power is the Watt. That's the rate of work or energy.

One watt means using 1 joule of energy (for example, push with a force of

1 newton through a distance of 1 meter), and doing that in exactly 1 second.
