## What is spring constant class 11?

The spring force is an example of a variable force, which is conservative. In an ideal spring, Fs = − kx , this force law for the spring is called Hooke’s law. The constant k is called the spring constant. Its unit is N m-1. The spring is said to be stiff if k is large and soft if k is small.

## How do you find the spring constant in an experiment?

W = kx. W is the weight of the added mass. Therefore, the spring constant k is the slope of the straight line W versus x plot. Weight is mass times the acceleration of gravity or W = mg where g is about 980 cm/sec2.

What is the formula for spring constant?

F=-k x
Formula of Spring Constant

Formula F=-k x
SI unit N.m-1

What is spring constant physics?

Spring constant is a characteristic of a spring which measures the ratio of the force affecting the spring to the displacement caused by it. In other words, it describes how stiff a spring is and how much it will stretch or compress.

### What is spring constant write its SI unit?

Spring Constant or force constant is defined as the applied force if the displacement in the spring is unity. Force constant is denoted by ‘k’. Its unit is Newton/metre.

### What is Hooke’s Law Class 11?

Hooke’s law states that the strain of the material is proportional to the applied stress within the elastic limit of that material. When the elastic materials are stretched, the atoms and molecules deform until stress is applied, and when the stress is removed, they return to their initial state.

What is helical spring class 11?

The helical spring is suspended vertically from a rigid support. A pointer is attached horizontally at the free end of the spring. A metre scale is kept vertically in such a way that the tip of the pointer is over the divisions of the scale, but does not touch the scale.

What is the spring constant in Hooke’s Law?

The proportional constant k is called the spring constant. It is a measure of the spring’s stiffness. When a spring is stretched or compressed, so that its length changes by an amount x from its equilibrium length, then it exerts a force F = -kx in a direction towards its equilibrium position.

## Is spring constant scalar or vector?

Is the force constant of a spring in Hooke’s law a vector quantity or scalar? It is a scalar constant for the spring.
