## What is the spring constant of rubber?

45.0N/m
Spring constant of the rubber band is k=45.0N/m.

## What is the constant in Coulomb’s law?

This equation is known as Coulomb’s law, and it describes the electrostatic force between charged objects. The constant of proportionality k is called Coulomb’s constant. In SI units, the constant k has the value. k = 8.99 × 10 9 N ⋅ m 2 /C 2. This means that the force between the particles is repulsive.

What is the spring constant of a spring?

Spring constant is a measure of the stiffness of a spring up to its limit of proportionality or elastic limit. The limit of proportionality refers to the point beyond which Hooke’s law is no longer true when stretching a material.

### What is the law of spring constant?

Hooke’s law is a law of physics that states that the force (F) needed to extend or compress a spring by some distance (x) scales linearly with respect to that distance—that is, Fs = kx, where k is a constant factor characteristic of the spring (i.e., its stiffness), and x is small compared to the total possible …

### Why does the spring constant change?

The more compliant (or softer) the spring is the more it moves for the same amount of force. The spring constant is simply the inverse of the compliance and sometimes also called stiffness. The stiffer the spring, the less it moves or, conversely, the more force is required to get the same displacement.

What is a common spring constant?

Spring constant is the amount of force required to move the spring a set amount of distance. Extension springs have the same units of measurements as compression springs, however torsion spring constant is calculated in force per 360 degrees of travel.

#### What is the constant k?

The Coulomb constant, the electric force constant, or the electrostatic constant (denoted ke, k or K) is a proportionality constant in electrostatics equations. In SI units it is equal to 8.9875517923(14)×109 kg⋅m3⋅s−2⋅C−2.

#### What affects the spring constant?

Factors affecting spring constant: Wire diameter: The diameter of the wire of the spring. Coil diameter: The diameters of the coils, depending on the stiffness of the spring. Free length: Length of the spring from equilibrium at rest.

Does a spring constant depend on how far the spring is stretched?

More generally, the spring constant of a spring is inversely proportional to the length of the spring, assuming we are talking about a spring of a particular material and thickness. That is because the spring constant and the length of the spring are inversely proportional.

## What kind of constant is k in Coulomb’s law?

K or εr is also called a dielectric constant of the medium in which the two charges are placed. History of Coulomb’s Law A French physicist Charles Augustin de Coulomb in 1785 coined a tangible relationship in mathematical form between two bodies that have been electrically charged.

## How is the spring constant of a spring determined?

The following is Hooke’s law formula for determining the spring constant of a spring: x is the displacement (m) (positive for displacement, negative for compression) A spring constant is a measure of a spring’s ability to resist compression and elongation. The higher the spring constant, the harder it is to compress or stretch it.

How does Coulomb’s law relate to free space?

According to Coulomb’s law, the force of attraction or repulsion between two charged bodies is directly proportional to the product of their charges and inversely proportional to the square of the distance between them. It acts along the line joining the two charges considered to be point charges. ε0 is the permittivity of free space.

### Are there any problems with the Coulomb law?

Problems on Coulombs Law Problem 1: Charges of magnitude 100 microcoulomb each are located in vacuum at the corners A, B and C of an equilateral triangle measuring 4 meters on each side. If the charge at A and C are positive and the charge B negative, what is the magnitude and direction of the total force on the charge at C?
