# What is power in simple words?

power, authority, jurisdiction, control, command, sway, dominion mean the right to govern or rule or determine. power implies possession of ability to wield force, authority, or influence. the power to mold public opinion. authority implies power for a specific purpose within specified limits.

## What is power in physics terms?

Power is equal to work divided by time. In this example, P = 9000 J / 60 s = 150 W . You can also use our power calculator to find work – simply insert the values of power and time.

## What is power in physics and give examples?

Advantages of mechanical energy: It is one of the most economical to generate, among all types of energy. It depends on itself to generate the power, so it is autonomous. It is more efficient than manual labor. It is a very versatile energy, so it has multiple applications and uses.

## What is power define clearly?

The capacity or ability to direct or influence the behavior of others or the course of events. “Power refers to a capacity that A has to influence the behavior of B so that B acts following A’s wishes”. Many scholars have given various definitions of power.

## What is a unit of power?

Power (P) is the rate at which energy is transferred or converted. Thus, power equals work divided by time (P = W / t). The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 – 1819).

## What is power and write its formula?

Power is defined as the rate of doing work. It is the ratio of the work done(W)and the time taken(t). Power(P)=Time(t)Work(W) The SI unit of power is Watt(W), in the honor of physicist James Watt.

## What is SI unit of power?

unit of power is watt (W). When a body does work at the rate of 1 joule per second, its power is 1 watt.

## Which of the following is the definition of power quizlet?

It is the potential of one individual to influence the behavior of another individual.

## What is used to calculate power?

Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.

## How are energy time and power related?

Power is how fast energy is used or transmitted – power is the amount of energy divided by the time it took to use the energy. Its unit is the watt, which is one joule per second of energy used.

## What’s the nature of power?

A century ago, the German sociologist Max Weber described power as “the probability that one actor in a social relationship will carry out his own will against the resistance of others.” This suggests power is more than achieving influence, and requires the ability to secure goals in the face of opposition.

## How do you calculate power in physics?

Power is equal to work divided by time. In this example, P = 9000 J / 60 s = 150 W .

## What are the 3 types of power?

Power refers to the ability to have one’s will carried out despite the resistance of others. According to Max Weber, the three types of legitimate authority are traditional, rational-legal, and charismatic.

## What is power and sources of power?

The five sources of power and influence are: reward power, coercive power, legitimate power, expert power and referent power. 1.Power of Reward.

## What types of power are there?

• Reward power.
• Coercive power.
• Legitimate power.
• Referent power.
• Expert power.

## How is force related to power?

Often it is convenient to calculate the average power. In the straightforward cases where a constant force moves an object at constant velocity, the power is just P = Fv.

## Is time a energy?

Time is not directly related to energy itself, but it is definitely related to many aspects of energy. For example, the direction of time (from past to future) can be determined by the flow of energy in the universe. This concept is known as entropy.

## What is this power factor?

Power factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). Apparent power, also known as demand, is the measure of the amount of power used to run machinery and equipment during a certain period. It is found by multiplying (kVA = V x A).

• P = E t.
• P = W t.
• P = V 2 R.

## Is power force times velocity?

Since work is force times displacement (W=F*d), and velocity is displacement over time (v=d/t), power equals force times velocity: P = F*v.

## What is average power?

Answer: Average power is defined as the ratio of total work done by the body to the total time taken by the body.

## What is power output?

Power Output means the average rate of electric energy delivery during one Metering Interval, converted to an hourly rate of electric energy delivery, in kWh per hour, that is equal to the product of Metered Energy for one Metering Interval, in kWh per Metering Interval, times the number of Metering Intervals in a one- …

## Is a joule a unit of power?

1 Joule (J) is the MKS unit of energy, equal to the force of one Newton acting through one meter. 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt.

## Which is the best description of power?

great or marked ability to do or act; strength; might; force. the possession of control or command over people; authority; influence: Words have tremendous power over our minds. political ascendancy or control in the government of a country, state, etc.: They attained power by overthrowing the legal government.

## What is the quantity of power?

In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity. Power is a scalar quantity.
