Acceleration is measured in which of the following units?

Acceleration is defined as the rate of change of velocity over time. In SI (International System of Units), velocity is measured in meters per second (m/s), and time is measured in seconds (s). To calculate acceleration, you take the change in velocity (in meters per second) and divide it by the time period over which that change occurs (in seconds).

Thus, the formula for acceleration is:

[ \text{Acceleration} = \frac{\text{Change in velocity}}{\text{Time}} ]

This leads to the unit of acceleration being meters per second squared (m/s²). This indicates how much the velocity of an object changes per unit of time. For example, an acceleration of 1 m/s² means that the velocity of an object increases by 1 meter per second every second.

Understanding this concept is crucial since acceleration plays a fundamental role in mechanics and is significantly involved in various engineering applications, particularly in the context of power engineering, where movement and changes in motion are often analyzed.
