What is the derivative of power in physics? In calculus terms, power is the derivative of work with respect to time. If work is done faster, power is higher. If work is done slower, power is smaller. 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's more, What is the power in physics?
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.
What is the derivation of energy?
Derivation of Kinetic Energy Formula by Calculus
Work done = Final K.E. - Initial K.E. The work done by a force is a measure of the change in kinetic energy of the body which proves the work-energy principle.
Related Question for What Is The Derivative Of Power In Physics?
What is the formula used to derive power?
Power = force multiplied by speed (velocity) P = F × v.
What is power and its derivation?
Power = unit of measure (Watt) W = work done by the body. t = time taken to do the work. Moreover, the standard unit of measuring power is Watt. According to the power formula, a unit of power is equal to a unit of work divided by a unit of time.
Is power the derivative of work?
W = ∫ F(x) · dx ; Work is the integral of force times displacement. P = dW/dt ; Power is the time derivative of work.

What is a derivation in physics?
Derivation means the action of obtaining something from a source or origin. Through derivation, we find a logical connection between a natural phenomenon and a mathematical description of that phenomenon.
What is the formula of energy?
What is the derivation of work?
The derivation of the work–energy principle begins with Newton's second law of motion and the resultant force on a particle. Computation of the scalar product of the forces with the velocity of the particle evaluates the instantaneous power added to the system.
What is power and example?
Power is defined as the ability to act or have influence over others. An example of power is the strength needed to run five miles. An example of power is the authority a local government has to collect taxes. The definition of power is operating electrically or having strength or force.
What is a power in math?
Power can be defined as a mathematical expression that can be used to represent exactly how many times a number should be used in a multiplication process. In simple words, it is an expression that describes repeated multiplication of the same given number.
What is power for class 9th?
Power of a body is defined as the rate of doing work by the body. unit of power is joule per second that is nothing but watt (W).
How is power related to work?
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 is the differential of work?
Is force and power the same?
Force is the fundamental result of an interaction between two objects, while power is an expression of energy consumed over time (work), of which force is an element. Force and power can both be described and measured, but a force is an actual physical phenomenon, and power in itself is not.
What is the best definition of power for you and why?
Answer: Explanation: Someone with power has physical strength or they're in control of things. Power comes from the Latin word potere, which means "to be able." But things with power are much more than able — they're able to exert a lot of force. Smenevacuundacy and 7 more users found this answer helpful.
What do you mean by power answer?
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 the formula for calculating power in physics?
P = E/t: This formula is also called the mechanical power equation. Here E stands for energy in joule and t stands for time in seconds. This formula states that the consumption of energy per unit of time is called power.
What is power write SI unit?
Power is defined as the rate of doing work.. It's SI unit is joule /sec or watt..
What is power very short answer?
Power is the rate of doing work, the amount of energy transferred per unit time. P = W/T (T - time)
What is power in science definition?
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 are the examples of derivation?
Here are some examples of words which are built up from smaller parts:
