Overview
Power is the rate at which work is done or energy is transferred. In physics, if work (W) is done over a period of time (t), the average power (P) is defined as P = W / t.
💡
Pro Tips
Doing the same amount of work in less time requires more power.
1 Horsepower (hp) is approximately 746 Watts.
Power is a scalar quantity, meaning it has magnitude but no direction.
In electrical terms, Power (P) = Voltage (V) × Current (I).

Fun Facts
"The term 'Horsepower' was coined by James Watt to compare the output of steam engines with the power of draft horses."
"A healthy human can produce roughly 50-100 Watts of power sustainably while exercising."
"The Saturn V rocket produced about 120 million Watts (120 MW) of power during liftoff."
