How many formulas are there for calculating acceleration?

Velocity v = s / T acceleration a = f / M = v2-v1 / T acceleration is the rate of change of velocity. In short, velocity = acceleration x time. For example, when an object accelerates from rest, the acceleration is the square of 10m per second. When it reaches the tenth second, the velocity should be the square of 10m per second x 10 seconds = 100 meters per second, That is to say, the speed can be obtained by the derivative of acceleration to time,
