The acceleration of an object is the rate at which its velocity changes with time. It is a vector quantity, meaning it has both magnitude and direction. The formula for acceleration is: Acceleration = (Change in velocity) / (Change in time) In terms of symbols, it can be written as: a = (v2 – v1) / (t2 – t1) where “a” is the acceleration, “v2” is the final velocity, “v1” is the initial velocity, “t2” is the final time, and “t1” is the initial time. Acceleration is measured in units of meters per second squared (m/s^2) in the International System of Units (SI). If the velocity of an object increases, the acceleration is positive, whereas if the velocity decreases, the acceleration is negative (but still refers to the rate of change in velocity). In summary, acceleration describes how quickly an object’s velocity is changing and in what direction. It is a fundamental concept in physics and is used to study the motion of objects.
