What is the equation for power with velocity?

In the straightforward cases where a constant force moves an object at constant velocity, the power is just P = Fv.

What is the formula for power?

Power is a measure of the amount of work that can be done in a given amount of time. Power equals work (J) divided by time (s). The SI unit for power is the watt (W), which equals 1 joule of work per second (J/s). Power may be measured in a unit called the horsepower.

Is power equal to MGH?

The formula for potential energy depends on the force acting on the two objects. For the gravitational force the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m / s2 at the surface of the earth) and h is the height in meters.

What is D in 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 does P VI mean?

electric power
The formula for electric power is given by. P = VI. where, P is the power. V is the potential difference in the circuit.

What is the formula of power in series?

The total power in a series circuit is equal to the SUM of the power dissipated by the individual resistors. Total power (PT) is defined as: PT = P1 + P2 + P3… Pn. As an example: A series circuit is made up of three resistors with resistance values of 5 ohms, 10 ohms, and 15 ohms.

How many formulas of power are there?

They are: P (watts) = V (volts) x I (amps) P (watts) = I2 (amps) x R (Ω) P (watts) = V2 (volts) ÷ R (Ω)

What is W MGH?

W= Force × displacement. =Weight × height. = mg × h. Thus, work done by force of gravity, W =mgh. Similarly, if the body is thrown up to a height h, the work done by gravity is.

How do you find velocity with mass and potential energy?

KE = (1/2)mv2

  1. KE = Energy (in Joules)
  2. m = mass (in kilograms)
  3. v = velocity (in meters/sec)
