- Hooke's Law. When an elastic object - such as a spring - is stretched, the increased length is called its extension. The extension of an elastic object is directly proportional to the force applied to it: F = k × e. F is the force in newtons, N. k is the 'spring constant' in newtons per metre, N/m. e is the extension in metres, m.

For a spring, is it F=kx or is it F=-kx? The force exerted by a spring is called a restoring force; it always acts to restore the spring toward equilibrium. In Hooke’s law, the negative sign on the spring’s force means that the force exerted by the spring opposes the spring’s displacement. Hooke’s law says. F = –kx.

Coulomb's Law In equation form, Coulomb's law can be stated as. where Q1 represents the quantity of charge on object 1 (in Coulombs), Q2 represents the quantity of charge on object 2 (in Coulombs), and d represents the distance of separation between the two objects (in meters). The symbol k is a proportionality constant known as the Coulomb's law constant.

Hookeâs Law The limit of proportionality is the is the point beyond which Hooke’s law is no longer true when stretching a material. The elastic limit is the point beyond which the material you are stretching becomes permanently stretched so that the material does not return to its original length when the force is removed.

- The property is described by an equation now known as Hooke's law. Hooke's law says that the restoring force (F) produced by the spring is proportional to the distance by which the spring has been lengthened (x). In equation form, Hooke's law looks like Equation 1: 1  F is the restoring force in newtons (N) 2  k is the spring constant in newtons per meter (N/m) 3  x is the distance the spring has been stretched (or compressed) from its neutral length in meters (m)

- Best Answer: force = kx [Hooke's Law] (where x is the amount of stretch) W(x) = work = 1/2 k x^2 = amount of work done in stretching the spring from its natural length to an amount of stretch of x. let L be the original length . (L < 8) 1 joule = 10000000 ergs stretching from 8 to 9: W(9-L) - W(8-L) = 0.05*10000000

Determine the Spring Constant Hooke's Law states that the restoring force of a spring is directly proportional to a small displacement. where x is the size of the displacement. The proportionality constant k is specific for each spring. The object of this virtual lab is to determine the spring constant k. Displacement is measured in centimeters.

Biography of Robert Hooke The drawing to the top left, of a flea observed through his microscope, was created by Hooke. Hooke was the first person to use the word cell to identify microscopic structures when he was describing cork. His other observations and discoveries include: Hooke's Law: A law of elasticity for solid bodies, which described how tension increases and decreases in a spring coil.

Homework Help: What does this equation mean? Physics Work. The s is arbitrary and simply denotes what F it is referring to. Yes, this is Hooke's law- the force due to a spring is proportional to the distance it is stretched or compressed. F is the force, and x is the amount of stretch or compression. k is not kinetic energy, it is the constant of proportionality.

Gauss' Law: Definition & Examples Gauss' law tells us that the flux is equal to the charge Q, over the permittivity of free space, epsilon-zero. But flux is also equal to the electric field E multiplied by the area of the surface A. So EA equals Q over epsilon-zero.

- Hooke’s Law College Physics Lab PH 141 Hooke's Law and the Work done by a Spring Purpose: To verify Hooke's law for springs, and determine the spring constant which characterizes the force exerted by a spring. To verify the relationship the amount of work done by a spring as it is stretched. Discussion: If a mass m on a spring is displaced from the equilibrium position (x 0 = 0) to a new position x, Hooke's law states that the spring will exert a restoring force on the mass.

Stress-strain Diagram An arbitrary strain of 0.05 mm/mm is frequently taken as the dividing line between these two classes. Stress-strain diagram of a medium-carbon structural steel. Proportional Limit (Hooke's Law) From the origin O to the point called proportional limit, the stress-strain curve is a straight line. This linear relation between elongation and the axial force causing was first noticed by Sir Robert Hooke in 1678 and is called Hooke's Law that within the proportional limit, the stress is directly proportional to strain or

Chemical Equilibria For systems that are not at equilibrium yet, the ratio calculated from the mass action law is called a reaction quotient Q. The Q values of a closed system have a tendency to reach a limiting value called equilibrium constant K over time. A system has a tendency to reach an equilibrium state.

Hooke's law 1 The deforming force may be applied to a solid by stretching, compressing, squeezing, bending, or twisting. Thus, a metal wire exhibits elastic behaviour according to Hooke’s law because the small increase in its length when stretched by an applied force doubles each time the force is doubled. 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.

- In this equation, and are the charges of the two particles, r is the distance between them, and k is a constant of proportionality. In a vacuum, this constant is Coulumb’s constant, , which is approximately N · m 2 / C 2.f we double one of the charges and double the value of r, we find: Doubling the charge on one of the particles doubles the electric force, but doubling the distance between the particles divides the force by four, so in all, the electric force is half as strong as before.

Motion of a Mass on a Spring The equation is T = 2•π•(m/k).5 where T is the period, m is the mass of the object attached to the spring, and k is the spring constant of the spring. The equation can be interpreted to mean that more massive objects will vibrate with a longer period.Their greater inertia means that it takes more time to complete a cycle.he spring constant (k in the Hooke's law equation) is the ratio of the F/x. If this ratio is low, then there will be a relatively large displacement for any given F value. Being displaced furthest from the equilibrium position will set the spring into a relatively high amplitude vibrational motion.
