For example the rate at which a lightbulb transforms electrical energy into heat and light is measured in watts Wthe more wattage the more power or equivalently the more. Power of contraction of clench muscles will be determined by a hand dynamometer. One horsepower is equal to approximately.

Give one partical. It should be noted that 1 J 1 N m 1 kg m 2 s 2. Show that 1 Km per hour.

It is the amount of energy consumed per unit time. Power 250 watts 14. The SI unit of power is Watt W.

Write the expression for the heat energy produced in a wire of resistance R and carrying current I. Power is what is consumed when a n. Power 1000 watts 15.

Having no direction it is a scalar quantity. Force 333 newtons work 5000 joules. Terms in this set 14 The unit of measurement of electrical power is the.

Find the Position by nature e dize of the image formed. Up to 24 cash back 7. Power is the amount of work done per unit time.

It is the amount of energy consumed per unit time. Work is defined as a force causing the movement or displacement of an object. Power is a scalar quantity which means that it gives us a quantity or amount of energy.

For example if a force of 5 newtons is applied to an object and moves 2 meters the work done will be 10 newton-meter or 10 Joule. We can define power as the rate of doing work or simply the work done in unit time. Amount of work done per unit of time.
