Acceleration is the rate of change of an object's velocity with respect to time. It is a measure of how much an object's speed is increasing or decreasing.
Acceleration can be calculated by dividing the change in velocity by the change in time. This can be represented by the formula a = (vf - vi) / t, where a is acceleration, vf is final velocity, vi is initial velocity, and t is time.
The unit of measurement for acceleration is meters per second squared (m/s²) in the SI system. It can also be expressed in other units such as feet per second squared (ft/s²) or kilometers per hour squared (km/h²).
Acceleration can affect an object's motion by changing its speed and/or direction. If an object is accelerating in the same direction as its velocity, it will speed up. If it is accelerating in the opposite direction, it will slow down. If the acceleration is in a perpendicular direction, it will change the object's direction of motion.
Some real-life examples of acceleration include a car accelerating from a stop sign, a ball falling due to gravity, a rocket launching into space, and a person riding a rollercoaster. Any time an object's speed or direction changes, there is acceleration involved.
