Acceleration is a change in speed or direction of motion. It occurs when an object speeds up, slows down, or changes direction. Acceleration is measured in units such as meters per second squared. It is part of how motion is described.

Acceleration is found in moving objects such as vehicles, falling objects, and rotating systems. It occurs in both natural and mechanical systems around the world. Scientists use acceleration to study motion.

Acceleration is present in many everyday activities and scientific observations. It is used in physics and motion studies. This concept helps describe changes in movement.
