## What is KX equal to?

Mathematically, Hooke’s law states that the applied force F equals a constant k times the displacement or change in length x, or F = kx. The value of k depends not only on the kind of elastic material under consideration but also on its dimensions and shape.

## What is half KX Square in spring?

Answer: w=(1/2) k x2. This work …… That means the stretched ( or compressed ) spring has energy potential energy . 1jaiz4 and 5 more users found this answer helpful.

## Why is there a half in elastic potential energy?

An easy but not very satidsfactory methos is to say Work done =F * d but the force is not constant. We could use ‘the average force’. Now the force increases from zero to a maximum F it turns out that we can take the average force to be 1/2 F. So this is where the half comes from.

## What is K in potential energy formula?

k = the spring constant, specific to the spring, with units N/m. Potential Energy: Elastic Formula Questions: 1) A spring, which has a spring constant k = 7.50 N/m, has been stretched 0.40 m from its equilibrium position.

## What is extension measured in?

extension (e), or increase in length, is measured in metres (m)

## 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.

## What is K and U in physics?

The work-energy theorem discussed in Chapter 7 relates the amount of work W to the change in the kinetic energy of the system. W = [Delta]K. The change in the potential energy of the system can now be related to the amount of work done on the system. [Delta]U = – [Delta]K = – W.

## What does K mean in physics?

Boltzmann constant
Boltzmann constant, (symbol k), a fundamental constant of physics occurring in nearly every statistical formulation of both classical and quantum physics. … The molar gas constant R is defined as Avogadro’s number times the Boltzmann constant.

## What is K in Hooke’s Law?

Hooke’s Law is used to determined the restorative force or the amount of elasticity. Larger distortion would result in a larger force. Hooke’s Law is expressed in the equation F = – k(x), in which k is the spring constant and x is the displacement.

## What is U and V in kinematics?

They are often referred to as the SUVAT equations, where “SUVAT” is an acronym from the variables: s = displacement, u = initial velocity, v = final velocity, a = acceleration, t = time.

## Why is u used for velocity?

Is it not wrong?” Answer: actually we usually use u or U for voltage; look at the following equations. For velocity we usually use small v; look at the following equations. For volumes we usually use large V; look at the following equations.

## What does U mean in science?

Uranium, a metallic chemical element. u, the unified atomic mass unit, used to express atomic and molecular masses.

## What is U in physics class 9?

u is initial velocity. v is the final velocity. a is acceleration. t is the time period.

## What does U mean in physics velocity?

Initial Velocity is the velocity at time interval t = 0 and it is represented by u. It is the velocity at which the motion starts.

## Can we use vu?

we can use v=u+at when value of 3 things are given then only we can find the value of the 4th thing. we can use s=ut+1/2at^2 when value of 3 things are given then only we can find the value of 4th one.

## What is Z in physics?

Z particle, massive electrically neutral carrier particle of the weak force that acts upon all known subatomic particles. It is the neutral partner of the electrically charged W particle. The Z particle has a mass of 91.19 gigaelectron volts (GeV; 109 eV), nearly 100 times that of the proton.

## What is the curly W in physics?

(mathematics, set theory) The first (countably) infinite ordinal number, its corresponding cardinal number ℵ0 or the set of natural numbers (the latter of which are often defined to equal the former).
