Question: What Is The Equation For Power In Physics?

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

What is the basic equation for power?

Power = force multiplied by speed (velocity) P = F × v.

What is power equal to equation?

Power can be expressed as P = Work/Change in Time, instead of P = Change in Energy/Change in Time, because the change in energy is basically the work done.

What is current formula?

The current formula is given as I = V/R. The SI unit of current is Ampere (Amp).

What is power 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 work done formula?

Mathematically, the concept of work done W equals the force f times the distance (d), that is W = f. d and if the force is exerted at an angle θ to the displacement, then work done is calculated as W = f. d cos θ.

What is SI unit of power?

The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 – 1819). One watt equals one joule per second (W = J / s).

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 current unit?

The SI unit of current is ampere which measures the flow of electric charge across a surface at the rate of one coulomb per second. Since the charge is measured in coulombs and time in seconds, so the unit is coulomb/Sec (C/s) or amp. Meanwhile, the formula for electric current is given as follows: I = V/R.

What does Q mean in physics?

q is the symbol used to represent charge, while n is a positive or negative integer, and e is the electronic charge, 1.60 x 1019 Coulombs.

What is resistivity formula?

Resistivity, commonly symbolized by the Greek letter rho, ρ, is quantitatively equal to the resistance R of a specimen such as a wire, multiplied by its cross-sectional area A, and divided by its length l; ρ = RA/l. The unit of resistance is the ohm.

What are the types of power?

The 5 Types of Power Summary

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

What is power explain?

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 the full meaning of power?

1: possession of control, authority, or influence over others. 2: a nation that has influence among other nations a foreign power. 3: the ability to act or produce an effect It’s in your power to change things. 4: the right to do something the president’s powers. 5: physical might: strength The wind grew in power
