If you just whack a mass on a spring with a stick, the initial motion may be complex, but the main response will be to bob up and down at its natural frequency.

## How do you solve a spring problem in physics?

## How do you calculate Springs in physics?

F = -kx. 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.

## Does Newton’s second law apply to Springs?

When a mass is attached to one end of a spring and the spring is stretched a distance x , the spring force increases in strength proportional to the stretch.

## What is the equation of motion for a spring?

my + by + ky = Fext. This is the differential equation that governs the motion of a mass-spring oscillator. To start, we consider on external force and no friction, my + ky = 0.

## What is the tension of a spring formula?

The tension in the chain is given by T = ( F perpendicular ) / 2 sin(θ); since θ is small, T is very large.

## What is Springs and Hooke’s Law?

Within certain limits, the force required to stretch an elastic object such as a metal spring is directly proportional to the extension of the spring. This is known as Hooke’s law and commonly written: F = − k x \boxedF=-kx F=−kx.

## What happens if you add to much weight to a spring?

More about Hooke’s law It says that if you apply a force to a spring, then the force stretches spring. And if you don’t stretch too much, Hooke’s law says that the amount of force you apply is proportional to the stretch. So, that means that if you apply twice the force, you get twice the stretch.

## How does mass affect the length of a spring?

The period of a spring-mass system is proportional to the square root of the mass and inversely proportional to the square root of the spring constant.

## What happens when too much force is applied to a spring?

If too much force is applied, one may stretch or compress a spring beyond a certain point that its deformation will occur. On subsequent release of the stress, the spring will return to a permanently deformed shape which will be different from its original shape.

## Do springs always obey Hooke’s law?

If the spring pitch (the space between coils) is constant, a conical spring’s force will vary non-linearly, meaning that it will not follow Hooke’s Law. However, spring pitch can also be varied to produce conical springs that do obey the law.

## Is Hooke’s law obeyed by springs?

Understood in terms of Hooke’s Law, this restoring force is generally proportional to the amount of “stretch” experienced. In addition to governing the behavior of springs, Hooke’s Law also applies in many other situations where an elastic body is deformed.

## Why do springs obey Hooke’s law?

Spring will obey Hooke’s law if the stretched or compressed distance is proportional to the force which has caused it.

## Does Newton’s third law apply to Springs?

Newton’s Third Law, for every action there is an equal and opposite reaction, is demonstrated with the help of Hooke’s Law, where the force on a spring is equal to the spring constant multiplied by the displacement from the equilibrium point of the spring.

## What is spring force physics?

Spring force is the force required or exerted to compress or stretch a spring upon any object that is attached to it. When an object applies a force to a spring, then the spring applies an equal and opposite force to the object. It always acts so as to restore mass back toward its equilibrium position.

## What is simple harmonic motion of a spring?

Simple harmonic motion can serve as a mathematical model for a variety of motions, but is typified by the oscillation of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke’s law. The motion is sinusoidal in time and demonstrates a single resonant frequency.

## What is the formula for tension physics?

Solution: We know that the force of tension is calculated using the formula T = mg + ma.

## How do you calculate tension value?

In other words, Tension (Ft) = Force of gravity (Fg) = m × g. Assuming a 10 kg weight, then, the tension force is 10 kg × 9.8 m/s2 = 98 Newtons.

## Is there a tension formula?

Tension force remains a gravitational force. If the body is moving upwards then the tension will be referred to as the T = W + ma. When the body goes down, the thickness is the same as T = W – ma. T = W if the discomfort is equal to body weight.

## What is the principle of working of a spring?

When a load is hung on the spring, it stretches and the spring’s extension is proportional to the weight of the object. The working principle of the spring balance is Hooke’s law which is F=−kx.

## What are the 3 types of springs?

Again, there are three classes of springs: linear (or constant rate) springs, variable rate springs, and constant force springs.

## What Hooke’s law tells us?

Generally, for small deformations, the stress and strain are proportional to each other, and this is known as Hooke’s Law. Hooke’s law states that the strain of the material is proportional to the applied stress within the elastic limit of that material.

## What factors affect the strength of a 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. The number of active coils: The number of coils that compress or stretch. Material: Material of the spring used to manufacture.

## Are springs affected by gravity?

Although gravity affects what the equilibrium extension will be, it is not the restoring force, so it does not affect the period of oscillation of a mass on a spring. However, gravity does affect the period of a pendulum.

## Why does gravity not affect spring?

The question was why doesn’t gravity affect the spring-mass system, and the answer is because gravity exerts a constant force and not one dependent on displacement.
