What is power define as?
Definition of power (Entry 1 of 3) 1a(1) : ability to act or produce an effect. (2) : ability to get extra-base hits. (3) : capacity for being acted upon or undergoing an effect.
What is the best definition of power in science?
We can define power as the rate of doing work, it is the work done in unit time. The SI unit of power is Watt (W) which is joules per second (J/s). Sometimes the power of motor vehicles and other machines is given in terms of Horsepower (hp), which is approximately equal to 745.7 watts.
What is power and energy?
Energy is what makes change happen and can be transferred form one object to another. Energy can also be transformed from one form 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 definition of power in thermodynamics?
Power is defined as the time rate of doing work. It is equivalent to the rate of the energy transfer. Power has units of energy per unit time. As with energy, power may be measured in numerous basic units, but the units are equivalent.
What is power by Brainly?
Brainly User. Explanation: Power is defined as the ability to act or have influence over others.
What is work and power?
Work, Energy and Power are fundamental concepts of Physics. Work is said to be done when a force (push or pull) applied to an object causes a displacement of the object. We define the capacity to do the work as energy. Power is the work done per unit of time.
What is power explain with unit?
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.
What is power in 10th class?
Power = Work Done/Time Taken. It is measured in Joule per second. Example. Suppose 20 Joules of work is done in 4 seconds. Power =Work Done/Time Taken.
What is power in physics simple?
power, in science and engineering, time rate of doing work or delivering energy, expressible as the amount of work done W, or energy transferred, divided by the time interval t—or W/t. A given amount of work can be done by a low-powered motor in a long time or by a high-powered motor in a short time.
What do you understand by power and authority?
Power is an entity or individual’s ability to control or direct others, while authority is influence that is predicated on perceived legitimacy. Max Weber studied power and authority, differentiating between the two concepts and formulating a system for classifying types of authority.
What is power class 9th?
Power is defined as rate of doing work. It is also defined as rate at which energy is consumed. SI unit of power is watt. Concept: Rate of Doing Work.
How do you find power?
Power is equal to work divided by time. In this example, P = 9000 J / 60 s = 150 W .
What is power science class 9?
What is power according to M Weber?
Weber defined power as the chance that an individual in a social relationship can achieve his or her own will even against the resistance of others. This is a very broad definition and includes a very wide range of types of power.
What is power in physical science?
power, in science and engineering, time rate of doing work or delivering energy, expressible as the amount of work done W, or energy transferred, divided by the time interval t—or W/t.
What is power in terms of force?
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. More power is seen when the system is both strong in force and fast in velocity.
When did Weber define power?
Max Weber defined power as ‘the probability that one actor within a social. relationship will be in a position to carry out his own will despite resistance, regardless of the basis on which this probability rests’ (Weber, 1978: 53). While.
What is power in simple words?
Power is the rate at which work is done or energy is transferred in a unit of time. Power is increased if work is done faster or energy is transferred in less time. In calculus terms, power is the derivative of work with respect to time. If work is done faster, power is higher.
What is the formula for power in physics?
F → = m a → {\\displaystyle {\\vec {F}}=m{\\vec {a}}}. In physics, power is the rate of doing work or of transferring heat, i.e. the amount of energy transferred or converted per unit time.
What is the meaning of the term “horsepower”?
Horsepower is often used to describe the power delivered by a machine. Horsepower is a unit of power in the British system of measurement. It is the power required to lift 550 pounds by one foot in one second and is about 746 watts.
What is the unit of power?
Power is a time-based quantity. Which is related to how fast a job is done. The formula for power is mentioned below. The unit for standard metric work is the Joule and the standard metric unit for time is the second, so the standard metric unit for power is a Joule / second, defined as a Watt and abbreviated W.
