What is the formula to find the power of a time?

Determine the time in which the work will be done. Here, we can take t = 60 s . Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W .

What is the formula for power required?

Standard Electrical Formulas Used for Power Consumption Calculations

What is D in W FD?

What is Work? For one-way motion in one dimension, this is expressed in equation form as W = Fd cos θ, where W is work, F is the magnitude of the force on the system, d is the magnitude of the displacement of the system, and θ is the angle between the force vector F and the displacement vector d.

How do you calculate energy and power?

The formula that links energy and power is: Energy = Power x Time. The unit of energy is the joule, the unit of power is the watt, and the unit of time is the second.

How do you find current when given voltage and power?

This can be approached in exactly the same way as the one above, only this time it is used for calculating power, voltage and current. The explanations here are that; Current equals Power divided by Voltage (I=P/V), Power equals Current times Voltage (P=VxI), and Voltage equals Power divided by Current (V=P/I).

What formula is W FD?

To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd. If the force is being exerted at an angle θ to the displacement, the work done is W = fd cos θ.

What is the formula for power?

Power is basically amount of energy spent or absorbed per second. Energy is nothing but the work done by you on the object. And Work/Energy = Force * Displacement. Where M = Mass of object ; G = gravitational acceleration. I will show you how this formula for power is derived. Force = mass * acceleration of the body.

How do you calculate power from force and time?

In a mechanical problem, power is the time derivative of energy or work. In the present context, power is the instantaneous product of force times distance divided by time: p = Power, watts. Because equals velocity, there is a more useful, alternate form of the above equation:

How do you calculate the power of a body?

Let us start from the formula which define power as the rate work is done. Power = Work / time and work done on a body is equal to the energy expended on it so; Power = Energy / time . Changing energy to kinetic energy the formula becomes;

How to calculate mass when potential energy height and acceleration is given?

Calculating the Mass when Potential Energy, Height and Acceleration due to Gravity is Given. m = P.E / gh
