What Is Simple Harmonic Motion?

Simple Harmonic Motion (SHM) occurs when an object moves back and forth around a central point in a smooth, repetitive way. Think about a swing, a pendulum, or the vibrating string of a guitar; they all move to and fro around a central position known as the equilibrium point.
This type of motion is also called oscillatory motion, and it’s one of the most important concepts in physics. Our harmonic motion calculator helps you easily analyse such movements and understand how force, mass, and frequency interact in SHM systems.

How to Use the Simple Harmonic Motion Calculator

You don’t need to memorise formulas or derive equations, just follow these simple steps to use the All Calculator SHM tool:

Step 1: Choose What You Want to Calculate
Select what you’d like to find, time period, frequency, or angular frequency, from the dropdown menu of the simple harmonic motion calculator.

Step 2: Enter Known Values
Input the values you already know, such as:
Mass (m)
Spring constant (k)
Pendulum length (L)
Gravity (g) – default value is 9.81 m/s²
Leave unknown fields empty; the calculator will figure those out for you.

Step 3: Click “Calculate”
Once you’ve entered the values, press the Calculate button. The result will appear instantly, with all units adjusted automatically.

How Does It Work? – SHM Made Simple

The All Calculator Simple Harmonic Motion Calculator uses real physics formulas to ensure accuracy and reliability. Here are the core equations behind its smart computation:

To Calculate Time Period:
T = 1/f or T = 2π√(m/k)

To Calculate Angular Frequency:
ω = 2πf or ω = √(k/m)

To Calculate Velocity:
v(t) = -Aω × sin(ωt + φ)

Where:
A = Amplitude (maximum displacement)
ω = Angular frequency
φ = Phase angle (0 if not specified)
f = Frequency
k = Spring constant
m = Mass

Examples – SHM Calculations

Example 1 – Mass-Spring System
Mass = 2 kg
Spring Constant = 50 N/m
Gravity = 9.81 m/s²
The calculator will instantly compute the time period (T), angular frequency (ω), and velocity.

Example 2 – Simple Pendulum System
Pendulum Length (L) = 1.5 m
Gravity (g) = 9.81 m/s²
The calculator will determine how long the pendulum takes to complete one oscillation.

Bonus Tip – Use Correct Units

To ensure accurate results, always use the correct SI units:
Time in seconds (s)
Mass in kilograms (kg)
Frequency in hertz (Hz)
Displacement in metres (m)
Spring constant in newtons per metre (N/m)
