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!

Power is defined as the rate at which work is done or energy is transferred. It is measured in watts (W) or joules per second (J/s).
No, power cannot be measured in Newtons. Newtons are a unit of force, while power is a unit of energy per unit time. However, power can be calculated using force and velocity, as in the equation P = F * v.
No, power and strength are two different concepts. Power is the rate at which work is done, while strength is the amount of force a body can exert. For example, a lightweight athlete can have more power than a heavier athlete, but the heavier athlete may have more strength.
Power can be measured using a device called a power meter, which measures the amount of energy being used or transferred per unit time. It can also be calculated using the equation P = W/t, where W is work and t is time.
Power is a scalar quantity, as it only has magnitude and no direction. This is because it is a measure of how much work or energy is being used or transferred, rather than the direction in which it is being applied.
