How would one label power? Is it in Newtons?

    How would one label power? Is it in Newtons? And also, if a car is balanced on a hill, what are two of the forces that are acting upon it. I have gravity of course, but does inertia also work? Thanks in advance!

    How do you call the force of this hill on the car?

    about power: recover the units yourself knowing that power is work per unit time and work is force times distance.

    balanced forces? j/s or Watts?

    It's in Watts.

    1 Watt = 1 Joule per second = 1 Newton metre per second.

    There's the force of the Earth pulling down on the car (i.e. gravity, or the weight force), and the force of the ground pushing up on the car (usually called the "normal reaction force").
