Here's why:
* Velocity: Velocity measures how fast an object is moving and in what direction. Its unit is meters per second (m/s).
* Acceleration: Acceleration measures how much the velocity changes over a certain period of time.
Let's break down the unit:
* Meters per second (m/s): This represents the change in velocity.
* Squared (s²): This represents the time over which the velocity changes.
Therefore, m/s² tells us how many meters per second the velocity changes each second.
Example:
* If a car accelerates at 2 m/s², it means its velocity increases by 2 meters per second every second.
* In the first second, the car's speed increases by 2 m/s.
* In the second second, the car's speed increases by another 2 m/s, and so on.
In summary:
* Acceleration is a change in velocity over time.
* Meters per second squared (m/s²) represents the rate at which velocity changes, providing a clear and concise unit for acceleration.
