P=v/f
=======================
Well, let's see.
Force = newton
Work = force x distance = newton-meter
Power = work/time = (newton-meter)/(second)
The first answer above says Power = (Velocity)/(force). Let's check it out.
Speed= length/time = meter/second
Force = newton
V/f = (meter)/(newton-second)
Power = (newton-meter)/(second)
We don't know what kind of monstrosity V/f is, but it's not power.
How about (force) x (speed) = (newton) x (meter/second) = (newton-meter)/(second).
That's a lot nicer.
In all its glory, Power = F · V .
You, the questioner, said 'velocity', not 'speed', so you're going to have to
face this for what it is ... the product of two vectors. Force is a vector, and
so is velocity, but power is not. The way you multiply two vectors and get
a scalar is by means of the 'vector dot-product'. The dot-product of force
and velocity is:
(magnitude of the force) times (magnitude of the velocity) times (cosine of the angle between them).
The reason for this is: If the force isn't pushing in the same direction as the velocity,
then not all of it produces power, only the part of it that points in the right direction.
If you're trying to push a heavy wagon and it's not moving fast enough, what
do you do ? You let your feet get farther behind the wagon, and you crouch
down so that your shoulders are lower and more in line with the wagon. The
reason you do that is: Only the part of the force that lines up with the motion
helps with the motion, so if you want to push faster, you get the force down to
where it lines up better with the motion. You reduce the angle between the
force and the motion. That makes the cosine of the angle greater, so the dot
product is greater. Even though the magnitude of the force hasn't changed,
the component of the force in the direction where you need it has become
greater, by reducing the angle between them.

How do you find power given force in physics?
Power can be calculated by multiplying the force applied to an object by the velocity at which the object moves. The formula for power is P = Fv, where P is power, F is force, and v is velocity. This equation shows the rate at which work is done on an object.
What formula relates force and power?
The formula that relates force and power is: Power = Force x Velocity. This equation describes the rate at which work is done, where power is the amount of work being done per unit of time, force is the amount of force being applied, and velocity is the speed at which the force is being applied.
What is The relationship between power force and velocity is?
Power is the amount of work done per unit of time, calculated as the product of force and velocity. In equation form, power = force x velocity. This relationship shows that the amount of power generated is dependent on both the force applied and the velocity at which the force is being exerted.
How is power related to force and velocity?
Power is the rate at which work is done or energy is transferred. It is calculated as the product of force and velocity, where power = force x velocity. This means that power increases with both force and velocity.
How power is dot product of force and velocity?
The dot product of force and velocity gives the power generated by the force on the object. It is calculated as the product of the magnitudes of force and velocity, multiplied by the cosine of the angle between them. This represents the rate at which work is done on the object by the force.

What is the product of force and velocity?
Impulse
What is the energy of torque?
Static torque is basically an applied force, but applied about a centre instead of in a straight line. Dynamic torque, such as that produced by an engine, is a force translated from a straight line (piston) to a circular path (crank) and since its a force at a velocity, its rated as power.
How power is dot product of force and velocity?
The dot product of force and velocity gives the power generated by the force on the object. It is calculated as the product of the magnitudes of force and velocity, multiplied by the cosine of the angle between them. This represents the rate at which work is done on the object by the force.
Is force x velocity equal to power?
No, force x velocity is equal to mechanical power only if the force and velocity are in the same direction. Otherwise, power is calculated by force x velocity x cos(theta), where theta is the angle between the force and velocity vectors.
What is called the product of force and velocity?
The product of force and velocity is called mechanical power. It is a measure of how quickly work is being done by a force on an object in motion.
What is the formula of power in terms of velocity?
Type your answer here... E=mC2 (so sorry. Above answer gives energy, not power) Power is energy per unit time. E = Wt E= energy W=power t= time so W=E/t
How is power related to force?
No. I may have the power to lift a heavy weight but until I do it does not become a power by force. Power is the result of some action. A racing car has the power to do 250 kl per hr, but until I start the engine, put the car in gear and move off showing just what power the car has. So power is the result of some other action.
How the power is the dot product of force and velocity?
The power is given by the dot product of force and velocity because it captures the component of force that is acting in the direction of velocity. This means that only the force that is contributing to the motion of the object is considered in calculating the power transferred to the object. The dot product helps isolate this specific component and quantify the rate at which work is being done.
