What is the si unit of acceleration?

The SI unit of acceleration is the meter per second squared (m/s^2). It measures the rate at which an object changes its velocity over time. Acceleration can be defined as the change in velocity divided by the time taken for that change to occur. Mathematically, acceleration is represented as a = (v-u)/t, where "a" is acceleration, "v" is final velocity, "u" is initial velocity, and "t" is the time interval.

Acceleration can have both positive and negative values. A positive acceleration implies an increase in velocity, while a negative acceleration (often referred to as deceleration) indicates a decrease in velocity or a change in direction.

The meter per second squared is derived from the SI base units of length (meter) and time (second). It represents how much an object's velocity changes per second. For example, if an object's velocity increases by 1 meter per second every second, its acceleration would be 1 m/s^2.

Acceleration is a crucial concept in physics and plays a significant role in various fields such as mechanics, engineering, and sports science.
