Equations for Wave Amplitude
Amplitude refers to the maximum change of a variable from its mean value (when the variable oscillates about this mean value). In to and fro motion of a particle about a mean position, it is the maximum displacement from its mean position. Similarly, amplitudes are defined for periodic pressure variations, periodic current or voltage variations,…

How Does the Spring Constant Depend on the Length?
Suppose we have a spring of 6 cm with a spring constant k. What happens if we split the spring into two bits of equal size? There will be a new spring constant for one of these shorter springs, which will be 2k. More generally, a spring’s spring constant is inversely proportional to the spring’s…

Spring Constant
Now, the Spring constant is defined as the force required to restore the spring to its original shape per unit of extension of the spring. This also means that after knowing the spring constant we can easily find how much force is needed to deform the spring. Because if we apply more force than what…

Hooke’s Law
Hooke’s law defines the relation between the force applied and the distance stretched in the spring. The force required to compress or extend a spring is directly proportional to the distance it is extended. This is based on Newton’s third law of motion which states that for every action, there is an equal and opposite…

Simple Harmonic Motion
Simple harmonic motion is basically the repeated back and forth movement through a central position, such that the maximum displacement on one side of that position is equal to the maximum displacement on the other side. Each complete vibration’s time interval is the same. The force responsible for the motion is always directed towards the…

Introduction of Spring Constant Formula
Springs are something that all of us are familiar with. We usually see them in pens, toys and other household objects. One of the distinct things that make a spring special is its ability to maintain it’s length even after stretching. It just comes back into its original shape and is fascinating. In this section,…

Solved Questions Using Acceleration Formula:
1. What will be the Acceleration of a Car if it Slows from 90 kmh��ℎ to a Stop in 10 sec? Here, u = 90 kmh��ℎ = 90×518=25ms290×518=25��2 because initially it was moving at a speed of 90 kmph then reached zero. Final Velocity ‘v’ = 0 kmph, and t = 10 seconds Now, applying…

Acceleration Formula
If r→�→represents displacement vector and v→=dr→dt�→=d�→d� represents the velocity, then; Acceleration: a→=dv−→dt=d2v−→−d2t�→=d�→d�=d2�→d2� In one dimensional motion, where x is the displacement, and v=drdt�=d�d� is the Velocity, then; a=dvdt=d2xd2t�=d�d�=d2�d2� Example 1: A car starts from rest and achieves a speed of 54 kmh��ℎ in 3 seconds. Find its Acceleration? Solution: v0�0 = 0, vt�� = 54…
