Here are questions dealing with human power. Sometimes the power of motor vehicles and other machines is given in terms of horsepower (hp), which is approximately equal to 745.7 watts. Considering the definition of power and the two ways to find it yields multiple ways to increase something's power :
Thus, the power of a machine is the work/time ratio for that particular machine. (a) if you follow a diet of 2000 food calories per day (2000 kc), what is your average rate of energy consumption in watts (power input)? Power is a scalar quantity.
Power is defined as the rate at which work is performed or energy is transferred. The power rating indicates the rate at which that machine can do work upon other objects. In the international system of units, the unit of power is the watt, equal to one joule per second. All machines are typically described by a power rating.
Increase its strength (use more force ) or get the same work done faster (decrease t or increase v ). Power is the amount of energy transferred or converted per unit time. Ability to control people and events: Power is expressible also as the product of the force applied to move an object and the speed of the object in the direction of the force.
The amount of political control a person or group has…. Power is the rate at which work is done or energy is transferred, measured in watts. The si unit of power is watt (w) which is joules per second (j/s). Learn about power by exploring its various types, formulas, and why efficiency matters.
