📖 Comprehensive Note
Speed is defined as the distance travelled per unit of time. It is a scalar quantity, meaning it only has magnitude and no direction.
Key Points from the Lyrics
- Verse 1: Speed measures how fast a body moves, not the path or direction.
- Chorus: Speed = Distance ÷ Time. It tells how fast an object is moving over a certain period.
- Verse 2: Example of calculation: distance divided by time gives speed. Different speeds can be observed in cars moving fast or slow.
- Scalar Nature: Speed does not have direction; only magnitude.
- Practical Examples: Cars, runners, and any moving object can have their speed measured with speedometers or calculations.
In conclusion, speed tells us how fast a body is moving along its path. It is fundamental in physics for understanding motion and solving kinematics problems.

| When a body moves along the way, | Introduces speed as the rate of motion. |
| How fast it goes is what we say. | Speed focuses on how quickly the body moves. |
| Not the path and not the sign, | Direction or path is irrelevant to speed. |
| Just how quick it beats the time. | Speed measures how fast a body moves over time. |
| Speed is the distance travelled per unit time. | Definition of speed. |
| Distance divided by the time you see, | Speed = Distance ÷ Time |
| Gives the speed of the motion clearly. | Example of speed calculation. |
| A car that moves both fast and slow, | Speed varies depending on the object's motion. |
| Shows the speed by how far it go. | Distance travelled over time determines speed. |

📌 Summary
Speed measures how fast a body moves along its path. It is the distance travelled divided by the time taken. Speed is a scalar quantity, only concerned with magnitude.
The relationship is expressed as: Speed = Distance ÷ Time. It is fundamental for motion analysis and kinematics.
Even if the object covers the same distance faster or slower, speed changes accordingly. Direction does not affect speed.
