The unit for magnitude of acceleration is meters per second squared, represented as m/s².
Acceleration is defined as the rate of change of velocity over time. In physics, when we talk about how quickly something speeds up or slows down, we are discussing acceleration. By definition, if a vehicle increases its speed from 0 to 60 kilometers per hour in 5 seconds, we can calculate the acceleration by finding the change in velocity (the final speed minus the initial speed) and dividing that by the time it took for that change to occur.
To express this rate of change, we use the unit of meters per second squared (m/s²). This means that for every second that passes, the velocity of the object changes by a certain number of meters per second. For example, if an object has an acceleration of 2 m/s², it means that every second, the object’s velocity increases by 2 meters per second. This unit is crucial in physics for understanding motion and forces acting on objects.
