# How is power defined in society?

## How is power defined in society?

In social science and politics, power is the capacity of an individual to influence the actions, beliefs, or conduct (behaviour) of others. The term authority is often used for power that is perceived as legitimate by the social structure, not to be confused with authoritarianism.

## What is the theory of power?

The standard theory is that power is the capacity for influence and that influence is based on the. control of resources valued or desired by others.

## What is the relationship between work and power?

Work is the energy needed to apply a force to move an object a particular distance, where force is parallel to the displacement. Power is the rate at which that work is done.

## What are the significant similarities and differences between work and power?

The main relationship or difference between the two is time. Work is the amount of energy necessary to move an object from one point to another. Imagine moving a table or seat from your living room to your dining room. On the other hand, power is the rate at which the energy is spent.

## What is the relationship between power and time?

The point is that for the same amount of work, power and time are inversely proportional. The power equation suggests that a more powerful engine can do the same amount of work in less time.

## Is power directly proportional to work?

Power is the rate at which work is performed determined by how long it takes to perform the work. Power is then directly proportional to the work done and inversely proportional to the time to do the work. Remembering that work is force times displacement (W = F*d), you can derive a corollary for the power equation.

## Is power is proportional to voltage and current?

By Ohm’s Law, if resistance (R) and temperature remain constant, then current (I) is directly proportional to the voltage (V). As per the power formula, if the power stays the same then current is inversely proportional to the voltage.

## Are power and area directly proportional?

In fact, a wave’s energy is directly proportional to its amplitude squared because W ∝ Fx = kx2. All these pertinent factors are included in the definition of intensity I as power per unit area: I=PA I = P A , where P is the power carried by the wave through area A.

## Is power equal to work?

Power is a rate at which work is done, or energy is used. It is equal to the amount of work done divided by the time it takes to do the work. The unit of power is the Watt (W), which is equal to a Joule per second (J/s).

## What is the difference between work and power?

Work is defined as the process of energy transfer to the motion of an object through the application of force. Power is defined as the amount of energy transferred in unit time.

## What is difference between power and energy?

Energy is what makes change happen and can be transferred form one object to another. Power is the rate at which energy is transferred. It is not energy but is often confused with energy. The watt is the most commonly used unit of measure for power.

## What is the similarities between work and energy?

What is one similarity between work and energy? – Answers. Energy is the ability to do work. Work describes the conversion of one form of energy into another -e.g. an electric motor does work when it converts electrical energy into kinetic energy.

## What is the difference between force work power and energy?

The major difference between force and power is that force is an action on a body or interaction of two bodies. While power is the amount of energy consumed during an action over the body.

## What is average power formula?

If the resistance is much larger than the reactance of the capacitor or inductor, the average power is a dc circuit equation of P=V2/R, where V replaces the rms voltage.

## What are the two basic kinds of energy?

Many forms of energy exist, but they all fall into two basic categories:

- Potential energy.
- Kinetic energy.

## What is relation between power and energy class 11?

What is the Difference Between Energy and Power? Energy is an object’s ability to complete work. Power refers to the rate at which an object can complete work.

## What formula relates work and power?

Force must act in the same direction as the object moves 14.1 Assessment Page 10 Question #2 What formula relates work and power? Power = Work / Time 14.1 Assessment Page 11 Question #3 A desk exerts an upward force to support a computer resting on it.

## Is power and heat the same?

Power is the rate in which work is done or energy is transferred over time. It is higher when work is done faster, lower when it’s slower. Whereas heat refers to energy that is transferred from a warmer substance or object to a cooler one.
