📖 Comprehensive Note
Non-uniform motion refers to the motion of a body in which it covers unequal distances in equal intervals of time.
In non-uniform motion, the speed of the object is not constant; it may increase or decrease over time. The distance travelled per second keeps changing.
Examples include:
- A car moving in traffic, accelerating and decelerating.
- A stone falling freely under gravity, speeding up as it falls.
Key points:
- Speed is variable.
- Distance per unit time is unequal.
- Observed in most real-life motions.

Verse 1
A car in traffic moving fast then slow,
Changing its speed as the minutes go.
Not the same distance each second in time,
This kind of motion is not uniform.
Chorus
Non-uniform motion is the
motion of a body in which
it covers unequal distances yeah
in equal intervals of time.
Uh uh uh yeah
Verse 2
A stone falling freely down to the ground,
Speed increasing as it moves around.
Each second longer distance it will show,
That motion is non-uniform, we know.
Chorus
Non-uniform motion is the
motion of a body in which
it covers unequal distances yeah
in equal intervals of time.
Uh uh uh yeah
Outro
When speed is changing, fast or slow,
The distance per second will never be so.

|---|---|
| A car in traffic moving fast then slow | The car’s speed changes due to traffic conditions. |
| Changing its speed as the minutes go | The speed is variable, not constant. |
| Not the same distance each second in time | Distance covered in equal time intervals is unequal. |
| This kind of motion is not uniform | Such motion is classified as non-uniform. |
| A stone falling freely down to the ground | An object under gravity accelerates as it falls. |
| Speed increasing as it moves around | The object covers more distance each second as it accelerates. |
| Each second longer distance it will show | Distance per second is not equal; speed is increasing. |
| When speed is changing, fast or slow | Non-uniform motion occurs whenever speed varies. |
💡 Mnemonic
FAST – to remember key points about non-uniform motion:
- F – Fluctuating speed (speed changes)
- A – Acceleration may vary
- S – Speed not constant
- T – Time intervals have unequal distances

🃏 Flashcards
What is non-uniform motion?
Motion in which a body covers unequal distances in equal intervals of time.
How does speed behave in non-uniform motion?
The speed is variable; it increases or decreases over time.
Give an example of non-uniform motion.
A car in traffic changing speed or a stone falling freely under gravity.
Is distance covered per second equal?
No, in non-uniform motion, distance per second is unequal.
Does non-uniform motion occur in real life?
Yes, most real-life motion is non-uniform.

📌 Summary
- Non-uniform motion occurs when a body covers unequal distances in equal time intervals.
- The speed of the body is variable, not constant.
- Distance covered per second changes over time.
- Examples: A car in traffic changing speed, a stone falling freely under gravity.
- Most real-life motions are non-uniform.
- Direction may or may not change; the key factor is the variation in speed.
- Non-uniform motion can be represented on distance-time graphs with curves or unequal slopes.
- Understanding non-uniform motion is essential for solving physics problems on acceleration and velocity.
