How do you find force with velocity and power?
power := t -> force(t) * velocity(t); If mass is expressed in kilograms, position in meters, and time in seconds, then force is expressed in Newtons and power in Watts.
What is the formula of force velocity?
F = m * (v/t), where “m” is the mass of the object, “v” is the desired velocity and t = Time.
How do you calculate power force?
The expression for power is work/time. And since the expression for work is force*displacement, the expression for power can be rewritten as (force*displacement)/time. Since the expression for velocity is displacement/time, the expression for power can be rewritten once more as force*velocity.
Is force and power the same?
The concepts of force and power seem to convey similar meanings and are often confused for each other. But in physics, they are not interchangeable. 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.
Is force-velocity linear?
Those data showed that the F-V relationship obtained from average force and velocity values could be described as a linear function (R2 = 0.997) with a negative slope (Figure 1).
What is power in terms of force?
Power in mechanical systems is the combination of forces and movement. In particular, power is the product of a force on an object and the object’s velocity, or the product of a torque on a shaft and the shaft’s angular velocity. Mechanical power is also described as the time derivative of work.
Is force mass velocity?
Mass is the amount of matter in an object and is expressed in kilograms. It states that the rate of change of velocity of an object is directly proportional to the force applied and takes place in the direction of the force. It is summarized by the equation: Force (N) = mass (kg) × acceleration (m/s²).
How do you find velocity with force mass and distance?
The distance traveled, S = (V^2 – Vo^2) / (2 a). Assume Vo = 0, then S = V^2 / (2 a) , and V = Sqrt [2 a S] , where a = F / m , so V = [2 F S / m] , where F is the force, “a” is the acceleration, “m” is the mass.
Is kwh a unit of power?
To put it simply, a kilowatt is a measure of power and a kilowatt-hour is a measure of energy; power is the rate at which something uses energy, and energy is the capacity to do work.
